4 Portuguese blue and white tiles made in the second half of the 17th century. All four tiles have some chips to corners and sides. 2 tiles have a drill-hole. These tiles were mostly used to cover walls from important buildings, chapels and churches. Size of Portuguese tiles is 14 x 14 cm each (5.5” square each tile) but Portuguese antique tiles in general are made primitively and therefore size, shape and thickness can vary a little. Backside of the tiles is cut as can be seen on the pictures; this is usually the case with 17th century Portuguese tiles. More on this tile in J.M. Dossantos Simoes, volume 1, tile P-231 page 42.
