"

Returning to England, Kenyon joined the archaeologist couple Tessa Wheeler and her husband Mortimer Wheeler on their excavation of the Romano-British settlement of Verulamium (St Albans), 20 miles North of London. Working there each summer between 1930 and 1935, Kenyon learned from Mortimer Wheeler the discipline of meticulously controlled and recorded stratigraphic excavation.[2] Wheeler entrusted her with the direction of the excavation of the Roman theatre.[citation needed]
