Old Rauma is a delightful town of wooden houses from the 18th through 20th centuries (about 600) each of which has its own name written on the side in gothic letters. The helpful folks in the tourist office, a short walk from the bus station, have materials in many languages about the town and region including a self-guided walking tour of the tour that should take a leisurely 2 hours to do. (Highly recommended). I was there in April but I understand the town can get very crowded with bus tours in the summer months. There are several homes that have been converted into musueums (the Merla House is the most interesting)and many shops (lace is their speciality) and restaurants in all price ranges. It's a lovely place to just wander around the narrow cobblestoned streets and enjoy the scenery. It's a 4 hour bus ride from Helsinki (two or three direct buses Monday through Saturday) or an hour and a half from Turku, which has more frequent bus service.
