The UCL-INSAP excavations on site D at Volubilis have revealed a series of houses dating to the early medieval period. The Roman levels were covered by a deep destruction deposit, which appears to have been the result of an earthquake which occurred towards the end of the fifth century. Reoccupation of the site began in the seventh century, with the construction of three one-roomed houses, with annexes or workshops. The main rooms are sizable measuring c. 4 × 10 metres, and in one case there is evidence for a loft over the living space. Hearths and domestic silos are found within the living spaces, which are floored with plaster and beaten earth. There is some evidence for glass production on the site during this phase: glass wasters and a mold for the production of glass beads were found. Towards the end of the eighth century the three houses were replaced with new ones, although the continuity of their plans suggests that there was no break in the occupation of the site. The construction of a road running east-west across the site might be linked to the Idrissid occupation of Walila, at site D on the plain below. By the end of the eighth century the site was deserted, and it was not reoccupied until the fourteenth century, when house composed of two long rooms end to end was built along its southern edge. Each room had a raised platform at one end, probably used as a bed, and a paved area at the other which served as a work space. The room was heated by a brasier. No further occupation is recorded until the nineteenth century, when there is trace of some small buildings on the eastern side of the site.
