Milad tower is a multi-purpose tower in the heart of Tehran. It is located in a complex which is consisted of shopping centers, play grounds, water fountains, foodcourts, a Dolfinarium, a concert hall and so many other places. The tower is similar to the Cn tower of the Toronto in the shape.
You can see the tower from almost every place of the city because of its height. Milad tower is built on the top of a hill and reaches the maximum height of 435 on the tip of the antenna.
It has 12 floors on the top which is formed of restaurants, museums and a roofless 360 degrees deck at the height of about 300 meters. There are telescope like binoculars installed on the deck, so you can see the city in much bigger size.
When you enter the area on the ground you see a beautiful garden with water fountains. Then you get your tickets and enter the building and you reach the shopping mall and interior fountains. (the ticket is about 2.5 to 3 us dollars) Then you get in the elevator which are really fast too and then you reach the balcony floor.
There is the roofless 360 deck where you can watch beautiful view of Tehran. I suggest that you visit the tower in the evening so you can have both day and night views of the city. (in the evening in summer And in the afternoon in winter)
There is a restaurant, museums and other must-visit places inside upper and lower floors of the balcony.

Tehran is a very big city with so many must-visit places. Milad tower is one of them Which i suggest you to visit for sure. I hope you enjoy your trip to Iran. Have a nice time. Good luck.
