From c.1928-1930 the museum recovered numerous burials in the clay diggings, north of the present Cowdray Avenue, including a tightly concentrated group in the southward extensions of the diggings, referred to on Hull's Roman Colchester map as 'Brickfield' and marked with hashers south of the railway.
