A Zoroastrian fire temple. This temple is dramatically set atop a rock on the outskirts of Isfahan and provides a commanding view of the city (although much of it is covered in smog). You can take one of the blue buses (ask at the drivers), which will take you there. Climbing it will be a challenge on flip-flops, impossible with them downhill.
The Fire Temple of Isfahan is a Sasanian era archaeological complex located on a hill of the same name about 8 kilometers west of the city center of Isfahan, Iran.

Holy Savior Cathedral - Սուրբ Ամենափրկիչ Վանք

Bethlehem Armenian Church
Another interesting combination of Persian and Armenian religious architecture, this large church completed in 1627 is full of stunning paintings and frescoes. Behind Jolfa Square, less than 5 minute walk from Vank Cathedral.
Popular picnic spot for locals. It's possible to climb up the mountain which will take about 3 hours return. Or catch a telecabin up for 200,000 rials at the lower chairlift station. Besides, there is a bowling underneath the telecabin station.
The Bridge of 33 Arches
1602. This is one of the most famous examples of Safavid bridge design, beautiful whether there is water underneath it or not. There is also a basic eatery at the northern end.
