Thorp Arch Trading Estate is a trading estate, with both industrial and retail space, 3 miles (5 km) south-east of Wetherby in the City of Leeds metropolitan borough, West Yorkshire, England. The estate occupies the major part of the site of a former Royal Ordnance Factory (ROF), ROF Thorpe Arch, in the parishes of Thorp Arch and Walton. There is evidence of its former use around the site which was similar in layout to the former ROF Aycliffe in Darlington, County Durham.
The Royal Ordnance Factory was built to supply British forces with munitions during the Second World War. The site was ideal, it had a railway running adjacent (the Harrogate to Church Fenton Line), open space and was not in a strategic bombing area. Railways sidings built (these are still evident in certain areas) and buildings constructed around them, many with flat concrete roofs. The retail park is constructed in semi-underground bunkers, with grassy banks running up the sides of the buildings.
