The Royal Palace of Lithuania (Lithuanian: Valdov r mai) was a palace in Vilnius, Lithuania, built in the 15th century for the rulers of the Grand Duchy of Lithuania. The Royal Palace in the Lower Castle evolved over the years and prospered during the 16th and mid-17th centuries. For four centuries the Palace was the political, administrative and cultural center of the Grand Duchy of Lithuania. It was demolished in 1801. A new palace has been under construction since 2002 on the site of the original building. The partially completed palace was opened on the 6th of July 2009. In the 13th and 14th centuries there were stone structures within the palace site; some archeologists believe that a wooden palace stood there as well. The stone Royal Palace was built in the 15th century, apparently after the major fire in 1419. The existing stone buildings and defensive structures of the Lower Castle, which blocked the construction, were demolished. The Royal Palace was built in Gothic style.
