Vesunna, Gallo-Roman archaeological site in Périgueux, France.

Vesunna is the Gallo-Roman archaeological site of Périgueux, in the south of the city. Its best-known monument is the Tour de Vésone, a 24-metre-high round tower of small flat stones and brick courses, with a row of small arched openings near the top; it is read as the temple of the city's protective goddess. The site also holds the remains of a domus discovered in 1959, now sheltered by Jean Nouvel's glass-and-metal museum opened in 2003, and traces of the amphitheatre in the Jardin des Arènes.

Discovered in 1959 during construction work, this site reveals the remains of the ancient capital of the Petrocores tribe, occupied from the first to fourth centuries AD, including structures with hypocaust heating systems and private baths.

The site's name comes from Vesunna, a local protective goddess probably linked to springs, honoured at the sacred Fontaine des Jameaux between the hills of Écornebœuf and Boissière. The Petrocorii, whose name is read as "four armies", worked iron according to Strabo and sent 5,000 warriors to Vercingetorix in 52 BC. The museum's 17-stop route covers the temple, amphitheatre, city walls, burial cult, trade, wall painting, heating systems, kitchen and baths.

The Vesunna Museum, designed by Jean Nouvel and opened in 2003, protects the ruins under a modern structure with walkways allowing visitors to directly explore the ancient remains and view collections of archaeological objects.

A perfectly preserved wooden pump was discovered in one of the site's wells, providing exceptional evidence of the advanced hydraulic techniques used by the inhabitants of this wealthy Gallo-Roman residence in Périgueux.
