The city was founded in 1715 by margrave Karl Wilhelm von Baden. The city was laid out on the drawing board. It consists of a central circle, containing the castle, and streets running towards the castle as radial "spokes". This pattern is still visible today. Due to the fan-like layout, Karlsruhe is known as the "fan city" (Fächerstadt).
The Rhine valley, where Karlsruhe is located, is the warmest part of Germany because it is only about 115 m above sea level and there are mountains in the east (black forest) and west (vogesen). Therefore, Karlsruhe has more sunny days than many other parts of Germany.
There isn't a lot of tourist traffic to Karlsruhe. Tourists generally tend to gravitate towards the cities of Heidelberg (50km to the north) and Freiburg (100km to the south), with their well-preserved old towns. It's a shame though, as Karlsruhe's radial layout is one of the best early examples of New Urbanism, and is really a joy to explore. Maybe that's a benefit to travelers who do venture there, as the number of visitors is low enough to be sort of a novelty for the locals.
Karlsruhe is home to the two highest federal courts of Germany, the Bundesverfassungsgericht (Federal constitutional court) and the Bundesgerichtshof (Supreme federal court). Because of this and other administrative facilities, Karlsruhe has a reputation as a city of civil servants.
Karlsruhe has a large technical university, as well as several other colleges. The presence of the technical university has promoted the city somewhat in the world of Free and Open Source Software: Karlsruhe was the home of LinuxTag  until 2005.
Baden-Airpark  is the nearest local airport, about 40km from the city. The airport is now served by low-cost carrier Ryanair, which offers cheap flights to several European destinations. There is a cheap airport shuttle bus (Baden-Airport-Express ) (leaving 8 times a day on weekdays, 3 times a day on saturdays, synchronized with the flight schedule) to Karlsruhe Main Station. One-way-tickets can be bought from the driver (9 EUR, cash only, accepted currency: euro); alternatively, you can take a train or a tram-train to Rastatt or Baden-Baden and take a connecting bus to Baden-Airport. Through-ticketing is available, for current prices and schedules see (Karlsruher Verkehrsverbund (Karlsruhe Area Mass Transit Authority) )
Frankfurt airport is Germany's biggest airport and is served by all major carriers that operate in Germany. It has a direct ICE high speed train connection to Karlsruhe (1 hour).
Stuttgart airport is reachable by train in one and a half hour.
The train station (Karlsruhe Hauptbahnhof) is located south of the city centre, with roughly 5-10 minutes by tram to the central market square, and direct tram links to other parts of the city. Karlsruhe is well linked to other larger cities by ICE high speed trains. The schedules for the inter-city connections can be found on the site of the Deutsche Bahn  (German railroads).
On foot: A lot to see in Karlsruhe is along Kaiserstrasse. Because all the streets radiate outward, the Marktplatz is a great place to start a walking tour of the city. If you go up or down Kaiserstrasse, you will find a great variety of shops and restaurants on both sides of the streets. If you go towards the Palace (right in front of you if you're in the Marktplatz), you can visit the city museum inside the castle, or the park right behind it, where the people of Karlsruhe congregate to picnic, play sports, and relax on nice days. Go farther and you can take a walk into the "Hardtwald" which has a lot of trails right near the city center. Go south relative to the Marktplatz and you will soon come upon Ettlinger Tor and the Staatstheater. Exploring on foot allows you the opportunity to go down the allees and smaller streets in Karlsruhe where you can find a wonderful variety of shops, kneipes, and restaurants.
Public transport: Karlsruhe has an excellent public transportation system called KVV; its mostly built on tram-trains(stadtbahn).This allows trains to run on tram track within the city or on railway track to serve the surrounding areas.An overview of the entire transport network can be downloaded here . A single ticket for a trip within the city limits costs 2.20€ for adults, 1.20€ for kids. Most tickets have to be stamped upon entering a tram and controllers are quite frequent. In particular, for longer distances outside of Karlsruhe buying the right ticket can be a bit challenging, but in front of the main train station as well as located at Marktplatz, you will find a KVV office that will be happy to assist you. Trains run late into the night, in particular on weekends, but almost every line stops for a few hours every night. Schedules and maps are posted on virtually every station: you can also find more information on fares and timetables on the KVV homepage .
Rental bikes: During the summer, spring and autumn rental bikes are available throughout the city. A mobile phone is used to rent a bike and it can be 'returned' (again, using the mobile phone) at any inner city corner. To rent a bike costs no more than 0.08€/min or 9.00€/day. More information is available at the Call a Bike page  (German only), a brochure in English can be downloaded here .

There are also special exhibitions from time to time. North of the palace is a vast park area, the palace garden (Schlosspark), where the locals hang out on summer days. On Saturdays, Sundays and holidays during the summer season you can also take a ride on the small train that runs through the gardens. Steam trains usually run on Sundays while dieselpowered trains operate on Saturdays. Entry to the gardens is free, the museum is €4 for adults.
There are several man-made lakes in towns around (10-20 km) Karlsruhe, e.g. Epplesee in Rheinstetten (no BBQ allowed!) and in Weingarten and Untergrombach. Going by bike is a flat one-hour trip by bicycle, and swimming combined with a barbecue is a nice thing on a hot summer day.
The Pyramid - on the Marktplatz, and the emblem of the city. It marks the place where Karl Wilhelm was buried, and is somewhat unremarkable.
Zoo - near the main station, opening hours vary throughout the year, but the main entrance is open at least M-Su 9AM-16PM, and longer in the summer months. The other entrances have shorter hours, check on the web page. The zoo is moderately large, and does have some special attractions. The price is €6.50. In the Zoo, there is an artificial mountain (the Lauterberg), and a memorial for the 49° N parallel. You can also ride small boats ("gondolettas") in the lake. A so-called water organ (music and fountains) plays every 30 minutes.
Durlach Nowadays a part of Karlsruhe it is much older (first mentioned in the 12th century) than Karlsruhe itself and has a charming medieval town-center. It can be easily reached by tram 1 in a quarter of an hour. A word of advice: calling an inhabitant of Durlach a "Karlsruher" is asking for trouble. From the Turmberg (tower hill), you have a nice view over the city and the Rhine valley.
Wildparkstadion, . The stadium where the Karlsruher Sport Club (KSC) plays all of their home games. If you are in Karlsruhe in the Fall or Spring, during the Bundesliga season, you should try to catch a KSC game during the weekend. KSC fans, including the "Ultras", are some of the loudest and most passionate fans in all of German football, and definitely make the experience a good one. To really get in the action purchase a ticket in the 'Stehplatz' (Standing section) and try to buy early, as these are very popular events and the tickets go quickly!edit
Kombilösung: This controversial project refers to the combination of a tram tunnel in Kaiserstrasse and a road tunnel in Kriegsstraße, allegedly the solution (Lösung) for public transport capacity problems in Karlsruhe. There is an information pavillon near the Staatstheater, and in the coming years there will be lots of construction in the city. Not a sight as such, but interesting for public transport geeks.
Bauhaus-Siedlung Dammerstock. The suburb Dammerstock has a residential area in the Bauhaus style, planned i.a. by the renowned architect Walter Gropius.edit
Go cycling. The city has developed a 20 point plan to become the cycling city in Germany. Many bike lanes and good direction signs for cyclicts are a visible mark. However, the activists of VCD and ADFC will be able to point out weaknesses and dangerous spots.

What to eat (if you want to try something typical):
Flammkuchen: kind of similar to pizza, but with a a much thinner pastry and topped with sour cream instead of tomato sauce. Most typical toppings are onions and bacon, but there are many variants (in particular some very tasty sweet ones that come flambéed). Just order one after the other (they get cold very fast), always sharing each one with everyone on the table.
Käsespätzle: a special kind of pasta in a heavy cheese sauce.
Gebratene Maultaschen: kind of like Ravioli, but much larger and fried with onions. May sound strange, but you really can't do much wrong with these.
Wurstsalat: Sausage Salad; well, its Germany after all. Comes with bread and is really quite tasty.
Hackepeter: Raw minced meat with fresh onions and bread. You don't get this very often (but for example at Vogelbräu).
Yufka Döner: A kind of döner but a wrap is used instead of proper bread. Sold in dozens of places it is probably the cheapest way to get a complete meal.
Where to eat:
Kräuterküche a small, modern German restaurant that offers a small selection of good food created in front of your eyes with fresh, biological ingredients. Its a good idea to call ahead and reserve a table. (Ritterstraße 10)
Die Kippe is one of the most typical student pubs in Karlsruhe. It offers cheap greasy food in a nice atmosphere. During the summer time they have a nice beer garden. Among other meals they serve a few regional foods. (Gottesauer Straße 23)

Café Bleu, Café Emaille. Two restaurants owned by the same purveyor that runs "Die Kippe". Both have the same menu as Die Kippe, but different atmospheres.

Hoepfner - like other cities in Germany, Karlsruhe has a few regional brands of beer, of which Hoepfner is the most famous. There is a brewery and Beer Garden at the east site of the town.

Alter Brauhof - a nice place to sit outside and have a beer (only a good place in summer), also offers decent food. Its not so well known, so you stand a good chance of finding a nice place even on a nice summer evening even on weekends. (Beiertheimer Allee 18a)
Carambolage - Special club in the near of the university and maybe the only place of the city where you can go out until 5AM during the week.
Z-10, Zaehringerstr. 10, . A bar run by local university students that is frequented by the Karlsruhe's student population. There are several local beers offered here for very cheap (think 1 - 1.50 euro) and also decent cocktails.

Check the website for hours as the bar is generally only open when school is in session.edit
Scruffy's. Scruffy's is Karlsruhe's best Irish Pub. The interior of the bar is reminiscent of the hold of an old ship and is a comfortable environment. There are a variety of beers and whiskeys, as well as good Irish music every week. Often the owner's band will play, always a treat. The bartenders and some of the patrons are native English speakers, so it's a good place to let the tourist's brain relax after speaking a lot of German! Just make sure you keep a good count on how many beers you order the owner occasionally miscounts. (Karlstr. 4, Across from the Europaplatz)edit
Dorfschänke, . The Dorfschänke is Karlsruhe's oldest Kneipe, and a good place to meet up with people. With the normal selection of beers and drinks, this is also a good place to see bands or to watch soccer outside during the summer.

(Am Künstlerhaus 33 )edit
Agostea is a nice but pricy club near the Kronenplatz with 2 dancefloors.
"Leonardo's Expresso Bar" directly located in the Center of Karlsruhe in the Zaehringerstrasse. There you can enjoy original Italian Coffee, good cocktails and also a lot of wines.

The Leonard, or also called Leo is one of the political Bars in Karlsruhe. High ranking Officials from the City, the Courts, the University and the Party are there often seen.
Bierakademie Karlsruhe, Douglasstraße 10, 76133 Karlsruhe, Germany (It's right's on the corner!), ☎ +49 (0) 721 / 27302, . Various. A small and pleasant bar and home of the Bierdiplom (4 litres) & Vorbierdiplom (2.6 litres), a "tour around the barrel" where guests pay in advance and get to drink 12 of the beers on offer in various quantities. There is a simple ruleset but the bar is very flexible. It makes for a fantastic evening for beer enthusiasts. Opening times vary, so you'll need to plan well. Normal. edit

In the south of the Marktplatz, at the end of the pedestrian zone, is a big shopping mall called "Ettlinger Tor". Definitely an alternative to the Kaiserstrasse, especially when the weather is bad.

Karlsruhe is maybe one of the safest cities in Germany especially the centre of the town. There are a lot of policemen walking and driving around, mainly because of the important courts. Maybe some suburbs should be avoided at night (Oberreut, Neureut and Daxlanden (not really)), but otherwise, one will feel safe in this city.
