Jupiter, his lover Ganymede and the four seasons are depicted in another mosaic in the house. The house was of palatial size, with 41 rooms covering an area of . A building dubbed the Gordian Palace is located further up the Decumanus Maximus. It was the largest building in the city and was probably the residence of the governor, rather than the emperor Gordian III; it was rebuilt during Gordian's reign in the mid-3rd century. It combined two separate houses to create a complex of 74 rooms with courtyards and private bathhouses serving both domestic and official functions. It also incorporated a colonnaded front with a dozen shops behind the colonnade, and an oil factory consisting of three oil presses and an oil store in the north-east corner of the complex. The decoration of the Gordian Palace is today quite plain with only a few scanty mosaics remaining. Despite its presumed high status, the floors seem to have been mostly rendered with opus sectile rather than decorated with mosaics. Inscriptions found in the palace testify to the city's decline and eventual fall. They record a series of treaties reached with the local Berber chieftains, increasing in number as the city became more vulnerable and the tribesmen pressed harder. By the time of the final treaty, just a few years before the fall of the city, the chieftains were being treated as virtual equals of Rome – an indication of how much Roman power in the area had declined. The last two inscribed altars, from 277 and 280, refer to a foederata et diuturna pax (a "federated and lasting peace"), though this proved to be a forlorn hope, as Volubilis fell soon afterwards. The House of Venus, towards the eastern side of the city under a prominent cypress tree, was one of the most luxurious residences in the city. It had a set of private baths and a richly decorated interior, with fine mosaics dating from the 2nd century AD showing animal and mythological scenes. There were mosaics in seven corridors and eight rooms. The central courtyard has a fanciful mosaic depicting racing chariots in a hippodrome, drawn by teams of peacocks, geese and ducks. The mosaic of Venus for which the house is named has been removed to Tangier, but in the next-door room is a still-extant mosaic showing Diana and a companion nymph being surprised by Actaeon while bathing.
