“…Flat tiles are present through-out France (Monier, 2011), from Perigord (Terreal, 2012b) to Ile-de-France (Monier, 2011), in the Lot department (Renaud, 2004) and in Bourgogne and Champagne (Le Pabic, 2000). Although northern mould interlocking tiles can even be found in the Marseille region (Monier, 2012) most are concentrated in the north (Monier, 2011). The southern mould interlocking tiles are also aimed either to the west, south-west or south of France.…”
