Constructed in the late 2nd century BC, this dwelling with a double atrium and peristyle was seriously damaged during Sulla's siege of 89 BC. It subsequently became property of the powerful Sextilii family, and the domus underwent major renovation, which was later followed by further modifications and extensions that saw the addition of a small bathing area and a bakery to the original nucleus of the structure. The main tetrastyle atrium has a monumental character, with four high Corinthian-Italic columns. The most noble and representative part of the domus however lies in the rooms which open onto the northern side of the large peristyle. Among them we find a large Corinthian oecus (parlour), supported by 10 columns and decorated with Second Style paintings. This room is flanked by two pairs of finely decorated cubicula, one of which houses a splendid mosaic whose central panel, depicting Theseus and the Minotaur, is framed by the labyrinth motif which gives the house its conventional name.
