Groningen is a city in the Netherlands with 190,000 inhabitants and is the capital of the northern province of Groningen. Groningen was founded around 950 A.D. at the site of a Roman camp and has a rich history, which can clearly be seen from the old medieval buildings in the down town area.
In the 13th century, when Groningen was an important trade centre, its inhabitants built a city wall to underline its authority. The city had a strong influence on the surrounding lands and made its dialect a common tongue. The most influential period of the city was the end of the 15th century, when the nearby province of Friesland was administered from Groningen. During these years, the Martini Tower was built, which loomed over the city at (then) 127 meters tall, making it the highest building in Europe at the time. The city's independence came to an end when it chose to join forces with the Spanish during the Eighty Years' War in 1594. It later switched sides, joining the Republic of the Seven United Netherlands.
In 1614, the University of Groningen was founded, initially only for religious education. In the same period the city expanded rapidly and a new city wall was built. That same city wall was tested during the Third Anglo-Dutch War in 1672, when the city was attacked fiercely by the bishop of Münster, Bernhard von Galen. The city walls resisted, an event which is celebrated with music and fireworks on 28 August (as "Groningens Ontzet" or "Bommen Berend").
The city did not escape the devastation of World War II. In particular, the main square, Grote Markt, was largely destroyed in April 1945, at the Battle of Groningen. However, the Martinitoren, its church, the Goudkantoor, and the city hall were not damaged. The battle there lasted several days.
The airport of Groningen (IATA: GRQ) is connected by Ryanair to some European airports, e.g. Milan Bergamo airport (twice weekly). In summer, more flights are available. City bus 2 serves the airport (50 minutes to town).
Groningen has three train stations, the central station (Station Groningen), Groningen Europapark and Groningen Noord. All trains eventually arrive at the central station; only a few trains stop at the smaller stations.
There are direct NS-trains from Schiphol airport, Utrecht and Rotterdam to Groningen (2.5 hours) and Amsterdam Centraal can be reached with one change (2h20m). A regional line runs west to Leeuwarden, which takes 50 minutes by slow train, or 35 minutes by fast train (once an hour). Other regional lines (all operated by Arriva) run to Delfzijl and Roodeschool. The entire tracks take about 40 minutes and all stop in Groningen Noord as well.
There is an international connection that terminates in Leer Bahnhof (Germany). Once over the border, you can change line to reach Bremen, Hamburg and Hanover. Note that the train to Leer is very local and takes about 1h15m to travel between the two stations. A special ticket is available for €10,30 or €17,50 return (September 2012) - you can only find it at the Arriva counter inside Groningen railway station . In Leer, the train connects to an RE going to Hanover via Oldenburg and Bremen.
The main bus station is right next to the central train station. All urban and regional buses start or end here.
There is a direct buslink to Bremen (starting at €7,50, one-way) and Oldenburg. Besides, there is a Eurolines bus stop.
You can get a ticket directly from and to Bremen Airport at the VVV office in Groningen, or book (and print) online. Prices vary depending on the hour of the day.
Driving in the old city, particularly within the central canal ring, is not the best option; parking is not always easy to find, and none of it is free.
There are several Park & Ride facilities; once of the biggest is on Sontweg, to the east of the city and near IKEA. It is clearly marked when driving on the ring road. Parking there is free, and for 1,50 euro a regular bus service takes you right to (and from) the Grote Markt, the heart of the city.
Like most cities in the Netherlands, Groningen's historic city center is surrounded by a canal, the diepenring. Most of the sights are within this area, and the Central Station is 50m outside it.
Within the diepenring, traffic is very restricted; Groningen's centre is designed to be as traffic-free as possible, and it is very difficult to drive and park within this area. Even resident parking permits are strictly rationed. However, the central area is compact and can be easily crossed on foot or with a bicycle.
Further out, Groningen has a loosely connected ring road, consisting of several N-roads forming a rather square ring shape around the centre. The city sprawls somewhat and crosses this ring in places, but most of the population live within this area.
Getting from any place in Groningen to the centre will take at most 20 minutes by bike. This makes the bike a fast, cheap and easy way to travel in Groningen. Don't get scared by the overwhelming amount of bicycles. The city houses tens of thousands of students, whose primary means of transportation is the bike. Be advised though; bicycle theft is pretty high so use a good lock (preferably two).
Bicycles are available for rent at a number of places around town, including a facility in the Central Station.
If you haven't got a bike the bus is the best option for distances you don't want to walk. All buses, which are operated by Qbuzz (www.qbuzz.nl), run through (or end on) Central station. Most buses have a stop at the Grote Markt. The major bus lines are listed below. Tickets are available by the driver (during off-peak periods you can buy a Eurokaartje, cost €1.50) or see the OV-chipkaart sections on the Netherlands page for other payment methods.

Line 8 runs from Central station via UMCG (hospital) to the Oosterpark.
Like most cities in The Netherlands, Groningen's city centre is surrounded by a canal. And like most cities in Europe, Groningen's museums are generally closed on Mondays. With those points in mind, here are some of the interesting sights:
The Groninger Museum. Just opposite train/bus station. Spectacular architecture. Hosts state of the art of contemporary art in the world. One of the five most progressive modern/contemporary art collections in the world.
Het Noordelijk Scheepvaartmuseum. The northern museum of water transport. Shows the history and role of transport over water until the 1970s.
Synagogue. The synagogue was built after the oriental design of the New Synagogue in Berlin. Shortly after WWII the Jewish community was forced to sell the synagogue since only a mere 7% of the entire Jewish community of Groningen survived the war. In 1981 the building was renovated and rehabilitated.
The Tabaksmuseum. Tobacco museum, 'roommate' of the scheepvaartmuseum. Collections moderately interesting, but housed in very beautiful, old, authentic warehouses.
The Universiteitsmuseum is a strange and wonderful little museum located just off Oude Kijk in 't Jatstraat. Temporary exhibitions, often of a technological bent, are held on the first floor; upstairs (past an elaborate stained-glass window in the stairwell) is an eclectic collection in the Victorian style, with everything from anatomical specimens and taxidermied animals to early scientific instruments.
The Aa-kerk. Beautiful church built in the middle ages.
The Rijksuniversiteit Groningen, the University of Groningen, is the second-oldest university in the Netherlands and one of three State Universities of the Netherlands. It was established in 1614. While the university has its share of modern buildings, both in and out of town, the Academiegebouw is an old and attractive building with a tower and worth strolling past.
The Grote Markt (great market) and the Vismarkt (fish market) are two large market squares in the center of the city.
There are several late-medieval Guest Houses (Gasthuizen) scattered through the city centre within the ring of canals. During daylight hours these courtyards can be visited for free. Be mindful that the houses themselves are not open to the public and that the people living in them enjoy their quiet and privacy. Visitors are welcome in the courtyards. Access is through gated doorways that will be unlocked during daylight hours and locked during the evening/night. The largest one is in the Pelsterstraat, next to the church and consists of several courtyards connected through archways. Another one is located behind the Vroom and Dreesman shopping centre in the Rode Weeshuisstraat (Red Orphanage Street). In the Peperstraat, near the end on the left when viewed from the Poelestraat, is the Peperstraat Guest House. Part of the medieval city wall is still visible from the courtyard. The St. Anthony Guesthouse is located opposite the police headquarters on the Rademarkt just south of Zuiderdiep.
The Old Roman Catholic Hospital or ORKZ when it was still in service
Oude RKZ, Old Roman Catholic Hospital. This is an old Roman Catholic hospital in the South of the city, in Helpman. The hospital itself was abandoned in 1978, after which it was squatted. Until 1986 the Oude RKZ was the largest squat in The Netherlands and possibly in the whole of Europe. In 1986 the government allowed the squat to be legalized. Nowadays it is a vibrant place where 250 people from all ages find a place to live and to share what is important. The former squat has cheap folk kitchens on Tuesdays, Thursdays, Fridays and Sundays. There are also 2 bars, a cinema, yoga and capoeira sessions and many many other things. Being a motor for the Dutch alternative and artist scene, the Oude RKZ is a well known place to many people from all over Europe. If you want to eat at the folk kitchen it's best to call on the same day to reserve a meal. Meals are served at 18:30 hrs and the number for the reservations is +31505257601.
Take a guided bike tour: the best way to discover Groningen.
Climb the Martini tower for a nice view over the city. It's one of the most famous sites in Groningen. Its name has nothing to do with the drink, by the way but refers to Saint Martinus. Though locals call the tower d' Olle Grieze which means 'the old grey one' and is related to its colour. Tickets are available in the VVV (tourist information) shop just over the road.
Take a canal cruisearound the historical center.
Like many Dutch cities, Groningen has beautiful canals around the centre. From the 1st of April until the 1st of Oktober it's possible to hire a canoe and paddle around the centre. It's a round trip that gives you a totally different view of Groningen since you are lower than the streets and you can pass very close along the many house boats in the city. Some bridges have a secret 'roof' that can only be seen when you pass under the bridge (or if you're standing at the right side when the bridge opens vertically). A tour around the centre takes about 1 - 2 hours, depending on how fit you are, how many stops you take for photo shootings, and water battles.* 't Peddeltje kanoverhuur, Oosterbrug (coming from the centre it's on the right side of the bridge, walk to the middle of the bridge and then down the stairs), ☎ 050-3130661, . 11:00 - 19:00. € 8 - 20. - GPS: N53° 12' 49.4274" E 6° 34' 25.215"

Visit the Noorderzon open-air theatrefestival in the second half of August, art, comedy, dance and theatre in the Noorderplantsoen.
See a band at Vera underground pop club, where Pearl Jam, Nirvana, Sonic Youth, the White Stripes and many others performed.
Visit the annual Eurosonic  and/or Noorderslag  music festivals, where dozens of bands from all over the world perform on various stages spread throughout the city.
The Dutch cartoon museum or 'Het Nederlands Stripmuseum' as it is called in Dutch (funny fact: strip = cartoon) has opened in 2004 and shows many cartoons made by Dutch cartoonists. It's also suitable to visit with children (not least because there's a McDonalds next-door with a play area), but also because they can learn how to draw cartoons by themselves. Het Nederlands Stripmuseum, Westerhaven 71, ☎ 050-3178470 (email@example.com), . +/- € 7.-. (N 53° 12' 57.351,E 6° 33' 24.015)

Every Friday from mid April until mid September skaters gather in Groningen to skate together. The group is accompanied by a rolling music boombox. The tours are quite easy to ride, though total beginners might find it a bit scary to have so many others around themselves. Each week another tour is chosen. It's possible to get an sms service to know if the Friday Fun Skate takes place or not. Lenght: 18 - 23 km. GPS: N 53° 13' 25.1364" E 6° 33' 19.6128"costs: free.
Take a free bus-ride on the National Day of Architecture organised on Saturday around 21st of June by GRAS-platfrom. Buses leave from Stadsschouwburg on Turfsingel from 11AM. on. Buses will take you to some highlights of newest architecture.
The Herestraat, the city's pedestrianised shopping street, runs south off the Grote Markt and contains most of the city's everyday shopping needs and 'standard' Dutch clothing stores and chains. This is where you'll find Hema, Blokker, de Bijenkorf, and so on.
Other shopping streets (Oosterstraat, A-kerkhof / Brugstraat, Folkingestraat, Stoeldraaierstraat / Oude Kijk in 't Jatstraat) extend out from the Grote Markt and the Vismarkt. Their side streets (Zwanestraat, Grote Kromme Elleboog) are often worth a look too. All streets within the central canal ring are low traffic due to restrictions - but watch out for cyclists, who don't often pay attention to pedestrian crossings.
The most picturesque shopping street is called the Folkingestraat; it runs south from the Korenbeurs (the former corn exchange) at the end of the Vismarkt towards the museum bridge and the Central Station. It has a lot of little shops full of firsthand and secondhand little gifts, intercultural foods and great books.
The lovely Oude Kijk in 't Jatstraat has different characteristic shops including plenty of art galleries, a travel bookshop, two branches of a great coffee and tea chain, an excellent independent bakery, a particularly nice cafe, shops selling toys and games, and a few second-hand furniture and clothes shops. It used also to have the best home made chocolate shop in town. However, that's now moved round the corner to...
... Grote Kromme Elleboog, which also has shops selling beer, herbs and spices, coffee, cooking utensils etc.
The centre of Groningen has many nice little cafes or restaurants where you can eat. Groningen is a real university city, so there are plenty of cafe-restaurants where you can eat for about €10.

De Drie Gezusters
Groningen's reputation as university town is borne out in its nightlife, which is comprehensive, with numerous options for drinking and clubbing. There are also several places to play pool/billiards. Most bars have the standard Dutch beers, but more and more international, especially Belgian, beers are beginning to have a presence. Bars in the down town area do not have fixed closing hours. Theoretically they can stay open for 24 hours a day, which a few bars do.
Big parties (usually with electronic music) in the whole Netherlands can be found listed on Partyflock (in Dutch).
