preserved; the mosaics of the two rooms that open onto the porch are dated to the Augustan age. The porch overlooks an apsidal nympheum which includes a swimming pool probably built in Imperial times. In the north-western part are thermal baths that were reduced from four to three rooms in the restructuring of the Augustan age. They are composed of a dressing room (apodyterium), a Turkish bath (laconicum) and a room for hot water bath (calidarium), covered with intact mosaic floors supported on columns of bricks to allow the circulation of hot air. Areas immediately south of the baths were a general sector for services directly connected with the decumanus by a narrow private road. The underground part of the house, the cryptoporticus, is accessed via a corridor to the east of the peristyle covered by a well preserved barrel vault. The underground environment was ventilated and lit from 18 windows that open at the level of the garden above. The function of the underground complex was especially the preservation of products such as wine and oil that needed a suitable environment. Next to the north-western side of the domus is a series of rooms built probably in the Hellenistic age. It is a complex of two or more buildings of still uncertain date and use. They are characterised by the presence of works of canalisation and different types of paving, using brickwork, tiles and local stone. Roman Arch of Publius Sulpicius Mundus In 2003 the foundations of a triumphal arch were discovered on the Decumanus at the west side of the Roman forum. Many fragments were found which allowed reconstruction of the arch, and a long inscription was also found which dedicated it to Publius Sulpicius Mundus who was a Roman senator in around 100 BC. The Temple The temple has an imposing base of sides 36.5 x 24.5 m. The temple had a continuous colonnade on all four sides, doubled on the front by four additional columns; it is preceded by a projection with a central staircase. The temple reveals at least two construction phases; the oldest (late 6th century BC) had numerous architectural terracottas with Ionic columns. In the early Roman Imperial age the temple was rebuilt, which involved the replacement of the wooden elements of the elevation with travertine structures and opus caementicium. Among the many elements of the elevation which have collapsed and are visible
