The town is built on the summit of a 310 m high conical hill or monticule.
The ancient route from Paris to Lyon passed through Vassy, and in the 13th century we find a mention of the town, under the name of Vasseium. In 1786 investigations were made into the possibility of coal mining here. In the 19th century the town gained a train station on the Auxerre-Avallon line, thanks to the factory of Honoré Gariel. He and his brother Hippolyte had created a company or Société able to produce hydraulic lime.
" A depot was founded in Paris; the cement, named from then on Ciment romain de Vassy, was employed by considerable businesses, and made the Société's fortune, though Honoré Gariel had by then ceased to take a part in the Société."
The hamlet surpassed the town's administrative center: The Gariel family endowed a town girls school (directed by the soeurs de la Providence, or sisters of Providence) with a chapel and a presbytery. As the population uniformly increased, a new church was begun in 1859 and finished in 1862.
