It is located in the Thun Palace, a historic building in the heart of the Malá Strana ("Lesser Town").

Holy Roman Emperor Rudolf II bequeathed a rebuilt house to one of his faithful servants, and the house was subsequently traded by winners and losers during the catastrophic upheavals of the Thirty Years' War.

In 1919, when Britain established relations with the new Republic of Czechoslovakia, the British leased the Thun Palace as a Residence for the Minister and the Legation offices.

But the main architectural features, artwork and great treasures of history remain, and the building and garden continue to be amongst the most beautiful locations in the city.

It was replaced by a new palace that was built in the early 19th century and now stands at Sněmovní 4 in Malá Strana.
