The İplikçi Mosque is the oldest Seljuk mosque in central Konya, completed in 1201–02 under the patronage of Şemseddin Altunaba. The building is simpler and more austere than the great Alâeddin mosque on the hill above — a single low rectangular hall with rows of brick piers carrying a flat wooden roof — and gives a clear picture of what an early Seljuk mosque looked like before the dynasty's architectural style had fully developed.
Tradition has it that Rumi preached here before moving to the larger Konya mosques and ultimately founding his own teaching circle. The mosque is still in active use; visitors are welcome outside prayer times, and the modest, restrained interior is a good antidote to the more visited monuments nearby. The name İplikçi — "spinner" or "thread-maker" — comes from the textile guild that used to gather around the mosque.
