Hamadan’s icon is the BuAli Sina (Avicenna) Mausoleum , a 1954 tower that looks something like a vast, unfinished concrete missile. It is loosely modelled on Qabus’s 1000-year-old tower in Gonbad-e Kavus, which BuAli probably saw inaugurated. Paying the entry fee (entry from west) allows you to see the single-room museum of Avicenna memorabilia, his tombstone, a small library and a display on medicinal herbs. But the tower itself is better observed from a distance.
