Evaluation by O Good of CA revealed evidence of low level, late post-medieval to early modern activity across the eastern part of the site in the form of a ditch, a large pit, two postholes and a short section of wall foundation. The features identified correlate well with the known development of the site in the mid–late 19th century by the Lion Brewery and its eventual demolition and redevelopment in the mid-20th century.

Excavation by D Hunt of the Wings Museum recovered finds associated with a Flying Fortress aircraft that crashed in the area on 19 March 1945.
