30 St Mary Axe 30 St Mary Axe (informally known as the Gherkin and previously as the Swiss Re Building) is a commercial skyscraper in London's primary financial district, the City of London. It was completed in December 2003 and opened in April 2004.[9] With 41 stories it is 180 metres (591Â ft) tall[3] and stands on the former sites of the Baltic Exchange and Chamber of Shipping, which were extensively damaged in 1992 by the explosion of a bomb placed by the Provisional IRA in St Mary Axe, the street from which the tower takes its name.[4][10]
King (chess) A king can move one square in any direction (horizontally, vertically, or diagonally) unless the square is already occupied by a friendly piece or the move would place the king in check. As a result, the opposing kings may never occupy adjacent squares (see opposition), but the king can give discovered check by unmasking a bishop, rook, or queen. The king is also involved in the special move of castling.
