The dining table at the Spanish embassy in Belgrave Square is 13.5 metres long and seats fifty people. It’s said to be the largest table (without leaves) in London. No. 24 Belgrave Square, once Downshire House, was acquired by the Spanish government in 1928. The table came with the house. The previous owner was William Pirrie, the 1st Viscount Pirrie, chairman of the shipbuilders Harland & Wolff and a one-time mayor of Belfast. It was in the dining-room of Downshire House in 1907 that Pirrie and Bruce Ismay, the managing director of the White Star Line, conceived their idea for three vast new ocean liners, the Olympic, the Britannic and the Titanic.
