Louvre

The Louvre, was one of the best art galleries in the universe, was located in Paris and it held the greatest art work in the universe; the Mona Lisa. The Doctor visited it in 1979 with Romana. (DW: City of Death) Lionel Harding visited it at least once, where he put a fight to see the Mona Lisa longer than the twenty seconds allowed for each viewing as he loved the painting. (SJA: Mona Lisa's Revenge)

Admiral Gaspard de Coligny's assassination, which helped set aflame the Catholic resentment towards the Huguenots and ignite the Massacre of St. Bartholomew's Day, was attempted as he returned from a meeting that took place at the Louvre with the  King of France (DW: The Massacre of St Bartholomew's Eve).
