New Delhi The Imperial New Delhi, a white palatial treasure designed by Sir Edwin Lutyens, has the best collection of 19th- and 20th-century Anglo-Indian art in the world. There are over 1,200 original works, some by British officers trained to draw military manoeuvres and others by their wives left behind in the cool temperatures of hill country. Updated art deco suite 268 has fascinating 1903 photographs showing the bejewelled Lord Curzon and friends astride elephants. GM is Pierre Jochem.

Athens The whole 548-room Athenaeum InterContinental Athens is one massive gallery for the collection of co-owner Dakis Joannou. Some works are gigantic, like George Lappas’ gentian-coloured cartwheeling man that dominates the main lobby. Others are humorous, such as Tassos Pavlopoulos’ Punishment of the Peevish Black Cat (1994). Reserve an Acropolis-facing room with access to the spacious club lounge and terrace. GM is Michael Koth.

Miami Four Seasons Hotel Miami showcases stunning Central and South American art collected by the hotel’s owners, Millennium Partners. A bulbous Seated Woman (2002), by Fernando Botero, graces the main seventh-floor lobby, and the employees’ dining room is named after him. Best rooms have views of Biscayne Bay. Regional GM is Ignacio Gomez-Tobar.

Sydney Among the more than 500 artworks at the Observatory Hotel are Australian landscapes by Charles Conder, Arthur Streeton and Tom Roberts, as well as botanical drawings by artists travelling with Captain Cook and sketches of the long journey from England by those on the first passenger ships. There is also an early 19th-century clock with a hand-painted face that inspired the hotel’s logo. GM Patrick Griffin coordinated the art collection, and corner suite 313 has a wraparound balcony with views of both Darling Harbour and Observatory Hill.
