There are actually three lost Junior grounds visible in the photo of Govan.
New Moore Park was originally two pitches running north/south. Many minor teams played there, including works teams, juveniles and the Govan Pleasant Sunday Afternoon team. The Ants took over in 1929 and turned it into one pitch running east/west. Harland & Wolff held the lease.
Above New Moore Park in the photo is the original Moore Park (aka Moorepark), lying derelict by this time and awaiting the construction of the "Wine Alley" housing estate. It lay on the west side of Broomloan Road and ran north/south. The Ants took it over in 1906 when Co-operative United FC (a Junior side) went bust. It was always described as a "model enclosure" and probably held five or six thousand fans after the Ants made considerable improvements. You had to go through a works yard to get to the payboxes from Broomloan Road. The Ants sub-let the ground to juvenile teams, including Govan Emerald and Govan Hibs.
Fifty yards to the north is Gymnasium Park, Benburb's second ground – just too far away from Moore Park to lob a brick or bottle. It was originally the Govan Police Sports Association ground, renamed by the Bens when they moved in 1912. It was a very tight little ground running east/west and abutting Broomloan Road. The railway goods yard fans out behind the north side of the park and there is a whitewashed factory building at the north-east corner. Fairfield Shipyard held the lease and their Junior team played there a few years before the Bens.
