Tehran, Golestan Palace.

Tehran doesn't have many tourist attractions, but Golestan Palace is the top highlight. Each area has separate fees, with the entrance fee for foreigners being around 12 euros. You can walk there from the city center. Inside, it is decorated with sparkling mirrors and is very gorgeous. The garden seen from the outside is also beautiful. Although Iran has a poor image now, you can see that it was once prosperous. I highly recommend visiting this place along with the Tehran Bazaar.
