DUBAI: The Arab Hall in London’s Leighton House Museum has been described by one of the English capital’s walking-tour guides as the city’s “most jaw-dropping room” The story of this sumptuous space begins with one of the Victorian era’s most-distinguished artists and travelers, Lord Frederic Leighton, who was only in his mid-thirties when he started building his red-brick house and studio in the Kensington neighborhood in 1864.
