The King and Queen then joined the invited guests for a high mass at Vilnius Cathedral, after which they attended the unveiling of a commemorative monument at the Palace of the Grand Dukes.
Lunch was served at the Museum of Applied Art, where the guests also visited a number of exhibitions.
The anniversary celebrations concluded with a performance by a choir of thousands in Vingio Park.
In his speech at the banquet, the King spoke about the historic relationship between Sweden and Lithuania, including how Scandinavian Vikings sailed to Lithuania as early as the 8th century to trade goods, and how the two countries now enjoy a close relationship as fellow members of the EU.
The anniversary celebrations were also attended by the presidents of Iceland, Finland, Estonia, Latvia, Poland, Ukraine and Georgia, as well as Cardinal Angelo Sodano from the Vatican City and the Swedish Minister for Foreign Affairs, Carl Bildt.
