Actually: far more exciting (as far as Latvia goes): The quadrennial folk song festival in Riga. Did you know that Lithuania has the world's largest collection of folks songs, and Latvia, the second largest? (Second-largest is good enough for me.)
Latvian was purely a spoken language -- a peasant's spoken language -- until the 19th century. Latvian and Lithuanian are loosely -- but only loosely -- related to the Finno-Ungric (& Estonian) language group.
