Palace of the Grand Dukes of Lithuania
The Palace of the Grand Dukes of Lithuania (Lithuanian: Lietuvos Didžiosios Kunigaikštystės valdovų rūmai Vilniaus žemutinėje pilyje; Polish: Zamek Dolny w Wilnie) is a palace in Vilnius, Lithuania. It was originally constructed in the 15th century for the rulers of the Grand Duchy of Lithuania and the future Kings of Poland. The palace, located in the lower castle of Vilnius, evolved over the years and prospered during the 16th and mid-17th centuries. For four centuries the palace was the political, administrative and cultural centre of the Polish–Lithuanian Commonwealth. It was demolished in 1801. Work on a new palace started in 2002 on the site of the original building and it took 16 years to complete it in 2018. The palace was rebuilt in Renaissance style to match the Cathedral of Vilnius and, according to the testimony of one of the couriers of Grand Duchess Bona Sforza, such initial reconstruction from 1520 to 1530 cost 100,000 gold ducats and was ordered by Grand Duke Sigismund I the Old. It is believed that the reconstruction was made for the proclamation ceremonies of Sigismund II Augustus, the only son of Sigismund I the Old, as the Grand Duke of Lithuania.
