London Millennium Tower London Millennium Tower The London Millennium Tower was one of several ideas for the site of the former Baltic Exchange at 30 St Mary Axe, City of London that had been destroyed beyond repair by a Provisional IRA bomb blast. Designed by Foster & Partners, for then owner Trafalgar House, the plan was for the building to be the tallest in Europe and the sixth tallest in the world at that time, behind the twin Petronas Towers in Malaysia, the Sears Tower (now called the Willis Tower) in Chicago, and the twin towers of the World Trade Center in New
St Mary Axe may derive from a combination of the church dedicated to the Virgin Mary and a neighbouring tavern which prominently displayed a sign with an image of an axe, or simply from the church name itself, which may have come from the axes used by the Worshipful Company of Skinners, who were patrons. The sign of an axe is reported to have been present over the east end of the church. The street St Mary Axe is now most notable for the Baltic Exchange at No. 38, and the "Gherkin" at No. 30, a distinctively shaped skyscraper built on the site
