SOUTERRAINS
selves have contrived some. As we shall see they did this, as well as make use of the natural provision supplied for their safety.
Of refuges there are two kinds, those patiently and laboriously excavated under the surface of the soil, and those either natural or contrived high up in the face of inaccessible cliffs.
Each shall be dealt with; they are different in character. The town of Saint Macaire on the Garonne is walled about. But the walls did not give to the citizens all the security they desired; the ramparts might be battered down, escaladed, or the gates burst open. Accordingly they excavated, beneath the town, a complete labyrinth of passages, chambers, halls, and store-rooms into which they might either retreat themselves or where they might secure their valuables in the event of the town being sacked.
At Alban in Tarn there are retreats of like nature under the houses, refuges at one time of the persecuted Albigenses, at another of the inhabitants secreting themselves and their goods from the Routiers. At Molières in Lot they are beneath the church, and the approximate date can be fixed when these were excavated, as Molières was founded in 1260.
Bourg-sur-Garonne is likewise honeycombed with such retreats, so is Aubeterre, of which more hereafter. The network of underground galleries and chambers is now closed, because the soft chalk rock has fallen in in several places. At Ingrandes-sur-Vienne there are three groups of these refuges, extending to a considerable distance. At Chateau Robin in the Touraine is a chalk cliff that rises above the road to the height of sixty feet and is crowned by a tumulus. In its face are two sets of caves, one superposed over the other. This upper cave or shelter is the most ancient, and dates from prehistoric times, but has been utilised much later. The lower cave is exposed by the
