Gallo-Roman theatre of Grand, Roman amphitheatre in Grand, France

The Gallo-Roman theatre of Grand is a semi-amphitheatre outside the village, south of the D 71e road towards Midrevaux, set against the slope of the combe de la Roche. Its cavea rises in three maeniana, now without seating, and is cut on the north by a straight facade with five blind arcades, two of which survive on the west. The arena, resting on natural ground, measures 34 by 50.80 m.

The theatre was built during the 1st century CE, when the Romans established a presence across Gaul and brought their building traditions with them. Grand was then an important religious and administrative centre, and this monument was part of a broader effort to shape the town.

The layout of the theatre, with its tiered seating facing a central stage, reflects how Romans and local Gauls shared public life in the same space. The open design made it a natural gathering point for the whole community, from performances to religious events.

The monument stands outside the village, south of the D 71e road towards Midrevaux, on the slopes of the combe de la Roche. The seating tiers have disappeared and the arena rests on the natural ground, so the surface is uneven; wear sturdy shoes. The remains are classified as a monument historique.

The arena's long axis runs east-west at 148 metres, matching 500 Roman feet of 29.6 cm; the short axis measures 64.50 metres. The upper seating was built only on the south side, so the monument was long read as a mixed theatre-amphitheatre. Jean-Claude Golvin classes it as a semi-amphitheatre.
