The Athenaeum is a family-owned five-star hotel overlooking Green Park.
Hope House was built at 116 Piccadilly in 1849/50 by Henry Pelham-Clinton, the 6th Duke of Newcastle. The name Athenaeum first appears around 1864 when the house was bought by the Junior Athenaeum Club. The house was redeveloped in the 1930s as an art deco apartment block, still called the Athenaeum.
In 1971 the Rank Organisation purchased the 1930s Athenaeum Court apartment block, opening it as The Athenaeum Hotel after a two-year refurbishment.
