The complex is composed of two adjoining houses which date back to the 2nd century BC and which today are used as a primary and secondary atrium. The most important paintings of the atrium are of high quality and which replaced previous decorations and theatrical scenes, in the Augustan era, inspired by the tragedies of Menander.

The whole environment is very elegant: the impluvium bath is covered in coloured marble and the compluvium that drains the rainwater is entirely rebuilt and decorated with pictorial terracotta water spouts. On one side of the impluvium there is the characteristic table held by three marble supports with lion-paw shaped feet that bear the engraved name of the original owner, Publius Servilius Casca Long(us), one of the conspirators who killed Caesar in 44 BC. The remarkable piece forms part of the confiscated property pertaining to the assassin of Julius Caesar and derived from the furnishings  of the wealthy owner of this house, a collector of valuable items, demonstrated also by a silver plate and a bronze statue found in the cabinets found in the atrium.

Date of excavation: 1912; 1926-1927.
