Adel is situated near the site of a Roman fort, the ancient road from Tadcaster to Ilkley passing nearby. (The footpath by the side of Long Causeway was said to be made from the original Roman stones, until they were removed by the council in the 1960s because they were unsafe. Some of the footpath has been replaced, starting at the junction between Long Causeway and Stairfoot Lane, and continuing up to the entrance of Bedquilts playing fields.) Several inscribed stones from the Romano-British period were discovered in Adel, also a number of Anglo-Saxon stones were discovered in the church foundations during restoration work in 1864. Some of these items are on display in the Leeds City Museum, Cookridge Street.
