Pair of tiles; 16th and 18th century. Polychrome ceramics. They show traces of plaster on the back. Measurements: 33 x 33 cm; 36 x 44 cm. Pair of polychrome ceramic tiles with a similar format, although they differ in size, one being more rectangular. In terms of ornamentation, one has a geometric design of straight lines arranged in the form of a grid, inside which concentric red motifs can be seen, which stand out in contrast to the blue of the lines. The piece appears to have lost its glaze. The other tile, from a later period, has figurative ornamentation, crowned at the top with a frieze-like composite image of palm trees and people.
