The Palace of the Grand Dukes of Lithuania is a historic palace originally built in the 15th century. It was the political and cultural hub of the Polish-Lithuanian Commonwealth for centuries until it was demolished in 1801. Fast forward to today, after a long reconstruction process, the palace has been rebuilt in a Renaissance style and now stands as a reminder of Lithuania's rich history. With its intricate architecture and fascinating past, this palace is definitely worth a visit for anyone interested in stepping back in time. It now houses a museum inside which you can enter for €12.
