Kaunas Castle
The first castle was built mid-14th century at the confluence of the rivers Nemunas and Neris. It was destroyed in 1401 and the new castle was constructed in the 15th and 16th centuries. It is the oldest building in Kaunas. Today the round tower houses an art gallery, and the castle hosts occasional festivals. The tip of the confluence is Santakos Park.

Cathedral of Sts Peter & Paul
This is first documented in 1413, in the reign of Vytautas the Great, but construction dragged on to 1624, nicely in time to get smashed up by the Russians and Swedes. It's 84 m long by 34 m wide and mostly red-brick Gothic, but refurbishment added Renaissance and Baroque features. It was promoted to a cathedral in 1895: notable burials include bishop and author Motiejus Valančius (1801-1875), poet Jonas Mačiulis (1862-1932) and Cardinal Vincentas Sladkevičius (1920-2000).
