Stadium
Kirkby Town played their home games at Simonswood Lane and later Kirkby Sports Centre. The Football Ground and the night club appeared in the 1991 Frank Clarke film Blonde Fist. Upon becoming Knowsley United, they relocated to Alt Park in Huyton which was previously used by Huyton RLFC from 1969 to 1984. Although by the time Huyton RLFC had vacated Alt Park the ground had become subject to vandalism and general disrepair, after Knowlsey United moved into Alt Park the ground underwent a series of renovations thanks largely to the involvement of the Orr family, who were the footballing proprietors of Kirkby Town FC and also the people responsible for the team's relocation to Huyton with Roby. Due to the initial success of Knowlsey United floodlights were installed and with the help of Knowsley Borough Council the clubhouse, grandstand & social club were recommissioned & upgraded as well. Alt Park was transformed into a respectable ground for a club the size of Knowsley United.
