Porvoo (Swedish: Borgå)  is a scenic small town 50 kilometers east of Helsinki, Finland. One of the most popular day trips from Helsinki, its picturesque city center of wooden houses is a proposed UNESCO World Heritage Site.
Finland's second oldest city (after Turku), Porvoo has been around since the 13th century, although most of the present buildings date to the 19th century. In 1809, Finland's nobles assembled at the Diet of Porvoo to affirm the country's conquest by Russia.
Today, tourists flock to pad about the cobbled narrow lanes of Old Porvoo (Vanha Porvoo), which has survived the sprawl of the modern city around it remarkably intact. The place is particularly popular in summer.
There are buses from Helsinki's Central Bus Station to Porvoo every 15-30 minutes. Standard/express services cost €10.30/13.20 one-way and take 55/65 minutes, so the surcharge is hardly worth it — the expresses just stop in Porvoo on their way to points further east.
There is no regular passenger train service to Porvoo, but the Porvoo Museum Railways run a vintage 1955 Lättähattu ("Flat Hat") Dm7 from Kerava to Porvoo and back on Saturdays in July/August only. The trip takes 1.5 hours and costs €15/25 one-way return for adults, half price for children, no reservations, cash only. As of 2009, the train leaves Kerava at 12:10 and sets off back from Porvoo at 4:00 PM. Kerava, in turn, can be reached in 20 min by regular commuter train from Helsinki's Central Railway Station.
M/s Runeberg cruises from Helsinki to Porvoo between May and September three to five times a week, departing at 10 AM and returning at 4 PM. The trip takes 3.5 hours one way and costs €25.00/36.00 one-way/return, half price for children. On Saturday, you can also opt to take the boat one way and the train back. The boat leaves from Linnalaituri on Helsinki's Market Square, opposite the President's palace.
Porvoo is easily accessed via the E18 expressway east from Helsinki towards Kotka and the Russian border. The other option is the old Porvoo road, Highway 170, but it's considerably slower and not particularly scenic.
Porvoo is best explored on foot: the pedestrianized Old Town is compact and all main attractions can be easily reached from the bus, ferry or train stations. Parents will, however, probably want to leave the baby carriage at home: the Old Town's streets are cobblestone and often hilly.
There used to be horse and carriage service, but it was shut down in 2010 due to financial problems. The Museum Railways also operate occasional steam train excursions.
The town is famed for its many wooden buildings, picturesquely perched by the Porvoo River (Finnish Porvoonjoki, Swedish Borgå å). These are concentrated in the old city (Fin: Vanha Porvoo, Swedish Borgå), a few hundred meters northwest of the modern city centre, and on a fine summer day a stroll around them is very delightful indeed. For the best view of the iconic red warehouses, cross the river and walk along the park on the other side.
Porvoo Cathedral (Porvoon tuomiokirkko). A heavy, squat, white stone building, this church wins no awards for architectural innovation, but it's among the oldest and largest in Finland, with parts dating back to the 11st century. Predating the Reformation, it was originally a Catholic church, but was somewhat crudely converted into a Protestant one later on by removing icons and painting over murals. The building was burned down four times between 1300 and 1700, and took a direct hit from a bomb in 1914 — miraculously, the bomb fell through the roof, but did not explode. The roof was burned by an arsonist in 2006, but the damage was repaired and it's now open again, with some of the Catholic-era murals restored in the process.edit

Kayaking and canoeing on the Porvoo River and in the nearby island is a popular summer pastime. It's even possible to make your way down all the way from Lahti, 90 km away. The stream is gentle and it's quite suitable for beginners, but don't venture out into the ocean unless you know what you're doing. Contact Kanotklubben Wiking  for more information.
In the old part of Porvoo there are lots of lovely little shops where you can buy anything from dollhouses to hand made jewelry. Many are, however, open only in the summer.
Brunberg, Välikatu 4, ☎ +358-19-5484235. Mon-Fri 10 AM-6 PM, Sat 9 AM-4 PM. One of Finland's most famous confectioners, this family-run business was founded in 1871 and is best known for their Pusu ("Kisses"), or giant puffs of flavored whipped cream encased in a thin chocolate shell. (Until recently, they were known somewhat politically incorrectly as "Negro Kisses".) Brunberg's liquorice (lakritsi) is another local favorite, and don't miss the chocolate truffles either. Most products are actually made at a factory on the outskirts of town (Teollisuustie 19 B, Mon-Fri 9 AM-5 PM, Sat 9 AM-3 PM), but their always-crowded Old Town shop is considerably more convenient.edit
Timbaali, Välikatu 8, ☎ +358-19-5231020, . Daily 11 AM-11 PM. Famous restaurant that specializes in a rather un-Finnish delicacy, namely snails. Snails from €10 per half dozen, mains (not all of which involve snails) from €20. Lovely indoor terrace in summer.edit

The measure of Porvoo
According to legend, the bailiff of Porvoo used a standard-sized measure to collect taxes of wheat or vodka from its citizens, but a specially altered box with a false bottom for passing them on to the Crown. He pocketed the difference and lived lavishly, and to this day the expression Porvoon mitta (lit. "the measure of Porvoo") lives on in Finnish to describe a generous or plentiful supply.

Four rooms decorated in various retro styles from Functional (as in the 1920s architectural movement) to Manor. Breakfast included.€180. edit
