Under Gallery
From Tardis Wiki, the free Doctor Who reference
The Under Gallery was situated beneath the National Gallery in London and was established by Elizabeth I to house dangerous art. In 2013 the Eleventh Doctor and Clara Oswald summoned there by UNIT to investigate a disturbance concerning broken Time Lord paintings. Upon arrival the Doctor discovered he had been made curator by the Queen, and that it was her wish that he be summoned should there be any disturbance there. It was later discovered that a group of Zygons had infiltrated the Under-Gallery by breaking out of the paintings, in reality Time Lord stasis cubes. (TV: The Day of the Doctor)
