Football architect Archibald Leitch was commissioned to redevelop the ground when Bradford City were promoted to the First Division in 1908. The stadium underwent few changes until the fatal fire on 11 May 1985, when 56 supporters were killed and at least 265 were injured. It underwent a £2.6 million redevelopment and was re-opened in December 1986. The ground underwent significant changes in the 1990s, and early 2000s, and now has a capacity of 25,136. The record attendance of 39,146 was set in 1911 for an FA Cup tie against Burnley, making it the oldest surviving attendance record at a Football League ground in the country. The highest attendance at Valley Parade, as it is now, was against Reading in the 2015 FA Cup Quarter-finals.
