Building and monument.
One walk around Sofia on 01.01.2019.
The building of the trade unions and the monument of the workers.
This building is built in an interesting way!
At first the stairwells and elevator shafts were built in the middle of the building. So to the top floor.
Then they started to place floor by floor from top to bottom.
I was a student in elementary school, they started building it.
It was completed in 1978 and is 99 m high.
