On the picture: The building inscription (mentioning date and builder) and a painted muqarnas (stalactite vaulting) above the entrance door.
‘Muqarnas’ is a decoration initiated in Anatolia by the Seljuk (in the 11th – 12th century). They imported it from Iran. Later on it continued to be used in the late-Seljuk architecture of the Beyliks (14th century) and by the Ottomans up to the 19th century.
