Baltic Exchange

The Baltic Exchange was an important listed building and historic landmark at 24–28 St Mary Axe in the City of London, occupied by the Baltic Exchange, a market for shipping, marine insurance, and information on maritime transportation. The building was known to some British architectural historians for its cathedral-like trading hall and the Baltic Exchange Memorial Glass, a stained glass war memorial. It was severely damaged by an IRA bomb on 10 April 1992 and, despite objections from architectural conservationists, was demolished with permission from the planning minister John Prescott to make way for the site now occupied by 30 St Mary Axe ("The Gherkin"). The stained glass, which had only suffered superficial damage in the bomb blast, has been restored and can be seen at the National Maritime Museum.

The building was designed by T.H. Smith and William Wimble and completed by George Trollope & Sons in 1903: it was subsequently listed as a Grade II* listed building.

On 10 April 1992 at 9:20 pm, the façade of the Exchange's offices at 24–28 St Mary Axe was partially demolished, and the rest of the building was extensively damaged in a huge Provisional Irish Republican Army (IRA) bomb attack. The one-ton bomb killed three people whilst 91 were wounded. The bombing came a day after the General Election.

Architectural conservationists wanted to reconstruct what remained of the building, as it was the last remaining exchange floor in the City of London. English Heritage, the government's statutory conservation adviser, and the City of London Corporation insisted that any redevelopment must restore the building's old façade onto St Mary Axe. In 1995, Baltic Exchange, unable to afford such an expensive undertaking alone, sold the site to Trafalgar House. The remaining sculptures and masonry of the structurally unstable façade block on the site were photographed and dismantled before the sale; the interior of the Exchange Hall, which was regarded as stable, was initially sealed from the elements in the hope that it would be preserved in situ in any new development, but the new owners subsequently dismantled it and stored it offsite in 1995–96.
