In 1994, Vilnius was declared a Unesco World Heritage Site. Today, visitors come to enjoy the preserved medieval buildings of the Old Town and to discover the city's many churches and museums.
In the heart of Vilnius, you can find the Republic of Užupis. This tiny republic (which is, of course, not recognized by any other country) is home to many Lithuanian artists. Explore the art galleries and make sure to also stop by the wall showcasing the Užupis constitution.
Close to Vilnius lies Trakai, famous for its island castle in the middle of the lake. The Karaites, a Turkic minority of Lithuania, live here, so this is a great place to learn more about them.
