A second 11th-century brick tomb tower in the old town, finished in 1056 CE — about thirty years after the Pir-e Alamdar on the next block. The proportions are slightly broader and the Kufic inscriptions slightly more elaborate, but the conical roof and the fluted body follow the same Seljuq vocabulary.
The name — "Forty Daughters" — is a local fairy-tale attribution; the dedicatory inscription actually names a Seljuq prince called Abu Shoja. Free to visit.
