Kleť, Stone observation tower on Klet Mountain, Czech Republic

Klet is a stone observation tower standing about 20 meters tall on a mountain in South Bohemia. From the summit, visitors can look out across the landscape and spot distant mountain ranges on clear days.

Josefova věž was built between 1821 and 1825 on the summit of Kleť (1084 m) above Český Krumlov, the first stone lookout tower in the Bohemian lands of Austria-Hungary. Duke Josef Johann Nepomuk of Schwarzenberg organised its construction, and the tower bears the name of its builder.

The tower is named after Duke Josef Johann Nepomuk of Schwarzenberg, who organised its construction. It stands beside the Tereziina chata hut, and the summit is also a television transmitter for multiplex 24 in DVB-T2.

The tower stands on the 1,084 m summit of Kleť in the Šumava foothills above Český Krumlov, with Tereziina chata next to it. The only viewing platform is 18 m up, reached by 110 steps inside the cylindrical stone shaft.

The tower doubles as a transmitter for multiplex 24 in DVB-T2, so its stone cylinder carries broadcast antennas alongside the viewing platform. From the 18-metre platform, reached by 110 steps, the view reaches the Alps in good visibility.
