The Gherkin is a building in the City of London named after and famous for its distinctive shape. Its modern architecture was designed by Norman Foster and was built between 2001 and 2003. Norman Foster is famous for utilising the laws of physics in designing many of his buildings. The walls of the Gherkin would allow air to enter the building for passive cooling. As this air warms up, it rises and is then let out of the building. The site where the Gherkin is built used to belong to the Baltic Exchange, the headquarters of the global marketplace for ship sales. In 1992, the site was damaged by bombs placed by the Provisional IRA. As there were many historic buildings in the area and only a few were damaged, the City of London governing body was insistent that any redevelopment must restore the old historic look. They later discovered that the amount of damage caused was too severe and so removed this restriction. The building was sold in 2007 for a sum of 630 million, making it the most expensive office building in the UK. The building was then put up for sale in 2014, initially at a lower price as its owners could not afford to pay loan repayments due to high interest rates and the devaluing of the British pound. It was bought by a Brazilian billionaire for 700 million.
