The tours

Down Street disused station tour (review)

Located in Hyde Park Corner and Green Park, Down Street had a short life as a working station from 1907 to 1932 but became critical to winning the Second World War when covertly transformed into the Railway Executive Committee’s bomb-proof bunker.

Visitors will experience the warren of narrow tunnels where the nation’s railways were coordinated and Prime Minister Winston Churchill took refuge secretly at the height of the Blitz.

Dates: Wednesdays, Thursdays, Fridays, Saturdays and Sundays, from 4 August to 11 September 2016; 24 November to 18 December 2016; 11 January to 5 March 2017

Clapham South: WW2 shelter (review)

Journey 180 steps underground to explore one of eight Second World War deep-level shelters that exist across London. Opened to the public in July 1944, Clapham South deep-level shelter has over a mile of subterranean passageways that reveal the extraordinary stories of those who sheltered here, from Londoners seeking refuge during the Blitz, to Caribbean migrants arriving on the Empire Windrush in 1948 and even thrifty visitors to the Festival of Britain in 1951.

Dates: Wednesday, Thursday, Fridays, Saturdays and Sundays, from 14 July to 21 Aug 2016; 2 March to 26 March 2017

55 Broadway: London’s first skyscraper (review)

Visitors will enjoy an expert led exclusive tour inside London’s first skyscraper, 55 Broadway at St. James’s Park. Radical and offensive to some when unveiled in 1929, this Grade I listed structure is now a wonderful example of Art Deco London.

This tour allows elite access to London Underground’s former headquarters and offers a new perspective on the capital city. Includes stunning rooftops views.

Dates: Saturdays and Sundays, 7/8 May, 4/5 June, 2/3 July, 13/14 August, 8/9 October, 19/20 November, 3/4 December 2016

Euston: The lost tunnels

Enter a labyrinth of dark and deserted passageways which were once used by the travelling public, and a gallery of preserved vintage advertising poster fragments that have been concealed for over 50 years.

Dates: Thursday, Fridays, Saturdays and Sundays, from 26 May to 19 June 2016; 22 September to 30 October 2016

Aldwych and Charing Cross

No tours this time due to planned works at those sites.
