Pebbles from the river were used to build the houses of Sainte Eulalie d’Olt, in the shadow of the Romanesque Church. The little stream that cuts the village in half, on its way to the Lot, is called the riu del cuèr (leather stream) because tanneries once lined its banks. A source of wealth from medieval times to well into the 17th-century, the gracious mansions of the main street are called the Curières Mansions, after the lucrative tanning trade.

'Olt' means Lot.
