The fortified medieval village of Gassin was first built around a single street located within the walls of the seigniorial castle. It corresponds to the current Rue de la Tasco, the oldest in the locality of the Var department. At the beginning of the 16th century, the village had a castle and a church and was surrounded by a suburb. It later gradually spread to the west, around the current Longue, Tubassière, Rollet de Garcin, Moulin à Huile, and Androuno streets. In the early 18th century, the land register mentioned a hospital north, a forge south, and two northern and western entrances in the fortified enclosure. Gassin acquired its current configuration in the 19th century and was extended to the south by a modern district designed by François Spoerry at the end of the 20th century.
