 The most striking examples are five extremely large rectangular tiles, in length, that form part of the façade of the Circumcision Room (Sünnet Odası) of the Topkapı Palace.Although the building dates from 1641, the tiles are believed to come from an earlier structure on the same site that was erected in 1527–1528.These large tiles are decorated with very elaborate designs that suggests the close involvement of the court designers.
