Edinburgh International Climbing Arena

Originally used for supplying stone to the Central Belt of Scotland due to its proximity to the Union Canal, the quarry expanded from around a third of its present size in 1853 to the current outline in 1895.

[5] When it opened in December 2003, the centre was the largest indoor climbing arena in the world, but problems during construction increased the final cost to £22 million.

[2][6] In March 2004 the centre went into receivership due to a leaky roof, poor management, and a lack of money, leaving a number of contractors unpaid.

[7][8] It was purchased by the City of Edinburgh Council in October 2005 for £3.87 million, and then closed in August 2006 to allow full completion of the venue.

[7] £6 million was spent overhauling the roof, the plumbing, improving the car park and converting an unopened scuba diving tank into a dedicated bouldering room.

The centre also houses Scottish National Judo Academy, and Canoe Scotland's Sprint Performance programme.

[29] On 20 April 2015 the Scottish National Party held their manifesto launch for the 2015 general election in the main climbing arena.
