Hamadan has been the land of great heroes and scientists: Cyrus the Great grew up here, Pharaortes was executed here, and after thousands of years the vestiges of the mythological walls surrounding the beautiful town of Daiakku (Deioces), the Medes' King, still can be seen there. The world-famous Iranian scientist, philosopher, and physician Abu Ali Sina known 1o the West as Avicenna, a prodigy who knew Koran by heart, lived in Hamadan for several years. He died in 1307. A large mausoleum built over his tomb in 1952, together with a library (which contains approximately 8,000 volumes of books) and a small museum devoted to his works are visited by most local and foreign tourists. A magnificent view of the city and the Mount Alvand can be seen from the roof of this museum.
Avicenna was above all a mathematician whose theories were taught in Europe until the 19th century. Today he would have been called a "pluridiscjplinary" scientist. His works as a poet and philosopher are still studied by Iranians and Orientalists.
On the left side gallery of the mausoleum there is a grave which is attributed to Abu Sa'id Dakhdukh, The grave of Aref-e Qazvini a famous early-twentieth century Iranian poet is also situated in an open yard close to the entrance of the building,

Actually., mausoleums are the best historical monuments of Hamadan for a tourist to visit, Like the whole city, the exterior of historic sites and mausoleums have been renewed in most cases by constructions inspired by spindle-shaped structure of Mongol towers, to the exclusion of all other features of these towers,
