Gaubert was an independent Municipal District until the end of the 19th century.
The slopes between the Cousson summit and the Bléone river have been occupied by humans since prehistoric times and numerous remains and artefacts from the Classic Antiquity period have been found there (Roman rooftiles, ceramics, tombs, etc.)

In the Middle Ages, the village was built on the hill and was surrounded by ramparts. The castle stood at the top of the hill, the church and the houses at its foot.

The only parts of the early church that remain today are those that were carved into the rock. The bases of the pillars are still clearly visible, as are a few graves. At that time, the chevet of the church was oriented to the east.  Later, the layout and use of the area evolved with more extensive settlements around Gaubert's embankments and ramparts; only a few remnants of the ramparts remain.
