city, southwestern Finland. It lies on the shore of Lake Vanaja, northwest of Helsinki. The city's name is derived from the castle of Hame, parts of which date from about 1250. The town, originally chartered in 1639, was first located north of the castle but moved to its present site, a little to the south, in 1779. In 1862 Hameenlinna became the northern terminus of Finland's first railroad.
