The stadium's first turf was cut by King George V, and it was first opened to the public on 28 April 1923. Much of Humphry Repton's original Wembley Park landscape was transformed in 1922–23 during preparations for the British Empire Exhibition of 1924–25. First known as the British Empire Exhibition Stadium[4] or simply Empire Stadium, it was built by Sir Robert McAlpine[5] for the British Empire Exhibition[6] of 1924 (extended to 1925).[7][8][9][10]
