Tour d'Assas, Residential tower in the Mosson district, Montpellier, France

Tour d'Assas is a 76-metre residential tower block in the Mosson district, north-west of Montpellier. It has 22 floors served by three lifts, with eight flats per landing. Its facade is a dense grid of identical rectangular windows and pale concrete panels, topped by a flat roof with a thin vertical mast.

The Tour d'Assas belongs to the second phase of works in the Mosson district, whose master urban plan was filed on 31 March 1969, the year after the Tours des Tritons went up. It is the major work of architect Guy Guillaume. In 1995 tenants sued the HLM landlord over overcharged service charges, and a co-ownership syndicate was created on 25 December. In 2015 about twenty residents demanded demolition; the tower was demolished in March 2025.

The tower's residents, many from the Dadès valley and Tineghir in Morocco, inspired Laure Pradal's 2009 documentary "Le village vertical", shown at festivals and on France 3 Régions. In 2015 about twenty women residents publicly denounced living conditions they called indecent and demanded the building's demolition.

The tower stands in the Mosson district, northwest of central Montpellier, behind a line of trees and a roundabout with a large circular concrete form. It is a residential block, not a public building, so access to the flats and lifts is reserved for residents and their guests. The building was demolished in March 2025, so there is no interior left to visit.

The tower's 22 floors are served by three lifts whose waiting times, in the evening, were reported in 1995 at ten to twenty-five minutes. The building was demolished in March 2025, so the concrete grid seen behind the trees and roundabout no longer stands.
