The building was organized with a series of spaces opening on to the central courtyard, provided with a deep well and surrounded by a large portico. Excavations of the portico have revealed the massive collapse of the terracotta covering of the roof, which must have been supported by a robust wooden framework. The covering was composed of roof-tiles, some of them with antefix and palmette, others made to cap the high columen of the roof, and others still in converse trapezoidal form to fit the corners, placed in a supporting position beneath the antefixes, with their female heads of high-quality manufacture.
