Audressein is a tiny village (pop ~120) in the foothills of the Pyrenees. One of the many old pilgrim routes to Santiago de Compostella once followed the valley.

When "Notre-Dame-de-Tramesaygues" was erected within the 14th century, there were still many pilgrims passing through here. As the confluence of two rivers is near the church "Tramesaygues" may mean "between waters".

The porch of the church has three entries. Black faces flank the main portal on either side.
