This one is not that tall either at 168m (552 ft), though it was built way back in 1971, so it was probably pretty tall for the time.
There is a similar building in Pécs, Hungary, where my wife's family lives: the Pécs Television Tower, the tallest building in Hungary. It was built in 1968/1973 and its height is 197 m. It includes also a non-revolving restaurant and an observation deck, but those are at a height of 75 m. The rest of the tower is not publicly accessible.
I have been to the observation deck several times with various visitors (grandchildren, brothers) over the years.
I guess you have been up there with Smallsteps, right?
Yep - that is quite similar :)
This one has a revolving restaurant on top that overlooks the city on one side, and one of the large lakes that frames the city on the other. Smallsteps enjoys it up there - but the restaurant is very expensive.
