Brockworth is situated in the Severn Valley between Gloucester and the Cotswold escarpment. The parish is divided by the line of Ermin Street, with the church and Court lying to the north. The Horsebere Brook winds its way past the site from the slopes of the Cotswolds to reach the Severn about 8 km away near Gloucester. Three other westward-flowing streams cross the low-lying undulating country between Churchdown Hill, 4-5 km due east of Gloucester, and Robinswood Hill to the south, both outliers of the Jurassic escarpment. Over the Lower Lias clay are spreads of Superficial Deposit, here composed of gravel and sand intermingled with a yellow clay.
