Baba Tahir was an 11th-century poet in Persian literature and an Iranian mystic. Most traditional sources call his dialect loosely Lorī, while the name commonly applied from an early date to verses of this kind, Fahlavīyāt. Roubène Abrahamian however found a close affinity with the dialect spoken at the present time by the Jews of Hamadan.
His tomb is located near the northern entrance of the city of Hamadan in Western Iran, in a park, surrounded by flowers and winding paths. The structure consists of twelve external pillars surrounding a central tower. It was reconstructed in 1970.
