The foundation of the Neo-Gothic King's Gates was laid in Kaliningrad in 1843. They were raised in the place where in the 18th century the Gumbinnen Gate stood. The facade of the King's Gates is decorated with sculptures of three rulers made of white sandstone: Czech King Otakar II, who participated in the founding of Koenigsberg; the first King of Prussia Frederick I, by order of which they created the Amber Room; and Duke of Prussia Albrecht I, who turned Germany into a secular state.
In Soviet times there was a bookshop in the King’s Gates, and in the 1990s a café was opened inside. Since 2005 the gate belongs to the Museum of the World Ocean. After the restoration the gates again became one of the symbols of the city. The exhibition "Grand Embassy", dedicated to the visit of Peter the Great to the city, to the diplomatic ties of Koenigsberg and the history of the city as a whole, is running in the gate room. The exposition on the second floor tells about the Koenigsberg Castle.
