6. Forma Urbis. The urban structure of Barcino

The city was constantly changing. Between the 1^st and 4^th centuries, the Roman administration ensured the maintenance of public spaces and services while private spaces were remodelled to meet the needs of the time.

The city’s structures responded to historical events. In the area near the forum, areas for services and shops were set up; the walls were reinforced in times of insecurity in the 3rd century; the great domus were remodelled in times of prosperity, and new public venues for worship emerged following the rise of Christianity.
