Babylon viewtower, Observation tower in Kladeruby nad Oslavou, Czech Republic.

Babylon viewtower is a stone observation structure that rises on Zelený kopec hill and reaches a height of about 25 meters. The building offers a viewing platform from which visitors can survey the Moravian landscape and the surrounding region.

The tower was built in 1831 at the initiative of Jindřich Vilém III. Haugwitz, then owner of the Náměšť nad Oslavou castle. It was originally meant to be one wooden storey taller, but that storey was damaged during the Austro-Prussian War of 1866 and the tower was lowered. Since 2002 it has belonged to the municipality of Kramolín.

The tower stands on Zelený kopec, a wooded hill at 491 m in the Kladeruby nad Oslavou cadastre, about 1.5 km east-southeast of Kramolín. The village of Kramolín owns it, and from 2002 to 2018 Jaroslav Odstrčil ran its operation. The viewing room at 18 m has a ceiling painted with zodiac motifs.

The viewing room sits 18 metres up, reached by 112 steps on an oak spiral staircase inside the stone tower. The tower stands on Zelený kopec (491 m) about 1.5 km east-southeast of Kramolín. Clear days reveal the Dukovany nuclear power plant, Pavlovské vrchy and the edge of Brno.

The tower was meant to be one wooden storey taller, but that storey was damaged during the Austro-Prussian War of 1866 and the tower was lowered. Inside, the ceiling of the viewing room at 18 metres is decorated with zodiac motifs.
