Croix de la Tourelle (Brasc -12-)
Cross of the Tourelle - 15th century

Brasc is on the border between the regions of Aveyron and Tarn.
At an altitude of 590 metres, the village of Brasc (established in 1845) is divided by a plateau on the West/ East, and the valley of the Tarn in the Northwest.

Brasc's name, originally, meant « heather ». But formerly, in language of « oc » (one of the three dialects of France with « oil » and « franco-provençal »), it was called « la pata negra » (the black paw) because of the colour of the land. A poor, uncultivated land where chestnut-trees grew and where they cultivated rye and later, potatoes.
