Together with residential areas intended for workers and factory owners, 25 different workshops have been identified, with a total of 182 square processing tanks.

They included an apodyterium, a frigidarium, a tepidarium, and a caldarium with an underground heating system, as well as swimming pools and an exercise room.

The complex also had four burial zones, including a mausoleum, with a columbarium made up of niches in the walls that were designed to hold urns containing the ashes of the dead.

This range of funerary contexts highlights the long duration of the occupation of this area, as well as the profound religious transformations experienced during the period.

In 1850 the excavations gained new impetus with the creation of the Lusitanian Archaeological Society, which carried out works in the Casas da Princesa (Houses of the Princess), where they found walls with paintings and floors with mosaics.
