Queen Victoria's Teahouse is located at Frogmore, in the Home Park of Windsor Castle, in Berkshire, England.

Frogmore House and its estate were bought by George III for his wife Queen Charlotte in 1792, although the land had formed part of the Windsor royal hunting ground since the reign of Henry VIII.

[1] Charlotte engaged James Wyatt to redesign the house and sought the advice of her Vice-Chamberlain, William Price, regarding the redevelopment of the grounds.

[b][5] During her long widowhood, when she rarely visited London, Victoria spent much of her time at Windsor and at Frogmore.

[8] Victoria also had the Indian Kiosk installed,[9][c] and engaged Thomas Willement to redecorate the Gothic Ruin originally designed by Wyatt and Princess Elizabeth.
