The main site of Oriel College incorporates four medieval halls: Bedel Hall, St Mary Hall, St Martin Hall, and Tackley's Inn, the last being the oldest standing medieval hall in Oxford. The façade of the east range forms a classical E shape comprising the college chapel, hall and undercroft. The exterior and interior of the ranges are topped by an alternating pattern of decorative gables. The gate house has a Perpendicular portal and canted Gothic oriel windows, with fan vaulting in the entrance. The room above has a particularly fine plaster ceiling and chimney piece of stucco caryatids and panelling interlaced with studded bands sprouting into large flowers.
