Winter Palace
From Tardis Wiki, the free Doctor Who reference
The Winter Palace was a building in Russia. A version of it existed in the Thirteen-Day Republic.
It was built by Catherine the Great to house her art collection, and enhanced by successive Tsars and Tsarinas, eventually considered to be the most elaborate of the Tsarist Palaces. In 1917, the last Tsar was overthrown and the first Soviet government moved in. (PROSE: The Book of the War)
