Si-o-se Pol

Si-o-se Pol or the Bridge of 33 Arches, also called the Allah-Verdi Khan Bridge, is one of the eleven bridges of Isfahan, Iran.

The Bridge of Allahverdi Khan across the Zayandeh River is a continuation of Chahar Bagh, the principal street in Isfahan. The Zayandeh River starts in the Zagros Mountains, flows from west to east through the heart of Isfahan, and dries up in the Kavir desert. It is highly ranked as being one of the most famous examples of Safavid bridge design.
