History

The building was designed by architect Richard Seifert and constructed from 1967 to 1969 by Grand Metropolitan Hotels as the Britannia Hotel.^[4] It has a classical red-brick facade facing Grosvenor Square, and a modern concrete, brick and glass facade facing Adam's Row. The hotel was renamed the Britannia Inter-Continental London in 1981, after Grand Metropolitan acquired Inter-Continental Hotels.

The hotel was bought by Millennium & Copthorne Hotels on 7 October 1996 and renamed the Millennium Britannia Hotel.^[5] It was renovated in 2000 and renamed the Millennium Hotel London Mayfair. The hotel's Pine Bar was the site of the poisoning of Alexander Litvinenko in 2006.^[6]

The hotel was renovated again beginning in November 2017, at an estimated cost of £50 million.^[7] It closed in July 2018 to complete the renovations and reopened on 9 September 2019 as The Biltmore Mayfair, LXR Hotels & Resorts^[2] managed by the LXR luxury division of Hilton. The hotel left Hilton on 1 May 2024 and now operates as part of The Biltmore Hotels brand of Millennium & Copthorne.^[8]
