- Antalya: Saat Kulesi, Yivli Minare and the minaret of Tekeli Mehmet Pasa Mosque
Yivli Minare was built under Seljuk Sultan Ala al-Din Kay Qubadh I (1220-1237). - Siena Cathedral
More interesting details on the ceiling of the Piccolomini Library. - Siena Cathedral
Ceiling of the Piccolomini Library, painted by Pinturicchio (1503). - Palazzo Vecchio
Officially, such decorations are called grotesque. - Palazzo Vecchio
Grotesque or not, I like them a lot.
