Limassol's lively old town district is the most interesting part of the city to explore. Right in the center, on the main square, is Limassol Castle, built in the 14th century on the site of an earlier Byzantine construction.
Some of the earlier fortifications can be seen just inside the walls. This is where Richard the Lionheart of England married Berengaria, and later, the Ottomans used it as a military base. The entire interior of the castle is now home to Limassol Medieval Museum with a fascinating collection of suits of armor, weaponry, religious icons, and tombstones.
