Laas

Laas, in the Osse valley, a sub-tributary of the Garonne via the Baïse, was once part of the ancient county of Pardiac, which was dependent on the county of Astarac.

The north-south ridge road is part of the ancient "route de César"; sometimes called the "Ténarèze", this prehistoric route in south-west France once linked Bordeaux to the central Pyrenees without crossing bridges or fords, and was one of the major cross-border and transhumance routes for several centuries. It was used and consolidated by the Romans.

The lords of Laas are recorded as early as the 12th century in the Berdoues cartulary. They had the right (for a fee) to give brides-to-be the headdress they wore on their wedding day. A Laas descendant lost his life against the Protestants during the siege of Mirande in 1577.

To the north of the church, there was once a seigniorial castle surrounded by moats, on the site of which the present castle was built. It dates back to the 17th-18th centuries and came into the possession of the Lamazère family, who were also lords of Laas, but in the 17th century.
