Mousterian settlements

In 1922 a large Mousterian site was discovered at La Garenne. The artefacts found there, date from the end of acheulean tradition (from 500,000 to 300,000 y.a.) to the end of mousterian (30,000 y.a.).^[3]

Celtic times

Trilithe du Vieux-Garçon (“The Old Boy”)

A Celtic oppidum over 22 acres wide stood on the hill north of the river, surveilling the « chemin Perré » ("stone path") where flint stones were used according to the Celtic method, and not stone slabs as per the Roman method.^[4]

Roman period

Triguères is a choice candidate for being the Vellaunodunum mentioned by Julius Caesar's in Commentarii de Bello Gallico.^[4][5][6] The remnants of a large Gallo-Roman town were found in the 1850-1860, notably an amphitheatre,^{[4][Note 1]} a cemetery in 1857,^[7] a source sanctuary at the moulin du Chemin in 1858,^{[7][Note 2]} Gallo-Roman villas at les Vallées and les Monts,^{[Note 3][Note 4]} a Gallo-Roman temple,^[4] an aqueduct and two public Roman baths.^[4]

Greater Triguères entirely disappeared in 451 when Attila passed through the valley, coming from Orléans which he failed to take (his first major drawback in his campaign) and on his way to a full defeat at the battle of the Catalaunian Plains.^[4] Triguères waited for six centuries to start its rebirth, and it never recovered its former splendour.^[7]

Middle Ages

Saint Alpais of Cudot and his legend precede Triguères' rebuilding, along with the Christian expansion. Saint-Martin church dates back from the end of the 11th century.

The Chatelet house was built in 1550.
