The İnce Minareli Medrese was built in 1264–67 by the Seljuk vizier Sahib Ata, and although it is structurally similar to Karatay, its portal is more famous: a riot of carved limestone, with two great calligraphic bands of Arabic looping in interlocking knots around the doorway. It is widely considered the masterpiece of Seljuk stone carving, the high point of the period's mature decorative style.
The building itself, on the west side of Alaeddin Hill, is small — a single domed central chamber with a few side rooms — but the dome's interior tilework, like Karatay's, is exceptional. The building now houses the Museum of Wood and Stone Carving, with a particular focus on Seljuk-era inlaid wooden doors, mihrabs, and minbars; many of the finest pieces of fourteenth-century woodcarving in Turkey are here.
Closed Mondays. The portal alone justifies a visit; pause to study the knotted calligraphy before entering.
