Trakai
Peninsula Castle
This followed a similar timeline to the island castle, raised against the Teutonic Knights, converted to a residence (where the Grand Duke was murdered in 1440, just to keep up the tradition) then to a nobles' prison before becoming derelict. However Dominican monks settled here and built a monastery and church in 1770. There's a small museum (just a few religious relics) but the castles' admin is also based here, so beware online maps that direct you here for the Island Castle. Most of the area is free to stroll 24 hours.
