built as a communication tower in 1969 to transmit tv and radio broadcasts, seoul tower is a must see for anyone going to seoul. Firstly you ride up to the tower on a cable car, which has a great view on the way up. Once you arrive at the tower, it's time to go to the top! In 30 seconds two expresselevators ascend to a height of 135 metres to the Observation Platform, where you can enjoy a buffet dinner at the revolving restaurant, and after dinner you can look out at seoul from every possible vantage point.
