Riga Radio & TV Tower is the tallest structure in the Baltics; 368.5m tall to the top of the spire (222m to the top of the roof). It is also the 3rd tallest TV tower in Europe, and the 11th tallest in the world. It was completed in 1986, only a few years before the fall of the Soviet rule.
The observation deck, however, is located on the two lowest floors of the structure itself at 97m height. It is situated on the Zakusala Island above the river Daugava, and is very complicated to reach the tower if don't have a car. At first you have to take the bus to a bridge above River Daugava, get off in the right direction (no signs show anything about what side), get down the bridge and walk some km on a pretty abandoned island, with almost no building or traffic (except for traffic school cars). When you reach the entrance, you have to wait for at least 20 minutes before someone receive you and let you buy a ticket, and finally the guide takes you to the diagonal (!) elevator. It felt just like the old Soviet times, but it was worth it! However, there are plans to refurbish and modernise the tower, and there were even a TV team making a documentary about the development during my visit.
