This peculiar sight is the Ješted Tower: a 94-meter tall structure on top of the Ješted Mountain near the town of Liberec in the Czech Republic.
The tower was built between 1963 and 1968 by architect Karel Hubácek. In its lower sections it houses a hotel and restaurant, the interiors of which are delightfully retro. In its upper sections are numerous transmitters for television broadcasts.
