St Andrew's @ Knighthead Park - Birmingham City

St Andrew's, known since 2024 for sponsorship reasons as St. Andrew's @ Knighthead Park, is an association football stadium in the Bordesley district of Birmingham, England. It has been the home ground of Birmingham City Football Club for more than a century. From 2018 to 2021, its sponsored name was St Andrew's Trillion Trophy Stadium.

Constructed and opened in 1906 to replace the Muntz Street ground, which had become too small to meet the club's needs, the original St Andrew's could hold an estimated 75,000 spectators, housed in one grandstand and a large uncovered terrace. Between 1906 and 1939 it was reported that a lot of construction work took place inside the ground and the official capacity was set at 68,000 at the start of the 1938-39 season. The attendance record, variously recorded as 66,844 or 67,341, was set at a 1939 FA Cup tie against Everton. During the Second World War, St Andrew's suffered bomb damage and the grandstand, housing a temporary fire station, burned down in an accidental fire. In the 1950s, the club replaced the stand and installed floodlights, and later erected a second small stand and roofed over the open terraces, but there were few further changes.
