Doubravka XIV., Observation tower in Prague, Czech Republic

Doubravka XIV is a 23.5-metre observation tower on Horka hill in the Čihadla forest park in Prague's Kyje district, designed by architect Martin Rajniš and his studio Huť architektury. Its triangular pyramid form is made of bent acacia wood, and 98 steps lead to a platform 20 metres up, where nine people can stand at once.

Construction began in 2017 and the tower opened to visitors in 2018, marking the first new observation structure built in Prague in decades. The project revived a tradition of public viewing points in the city.

The tower was partly funded by selling its 98 steps to the public, who could have personal messages inscribed on them. The acacia wood came from around Bzenecko in Moravia. The tower is part of a nature trail through the Čihadla park along the meandering Rokytka stream.

Access is free year-round with no admission fees required. Wear comfortable shoes since climbing all the steps involves regular physical exertion.

The tower was built from over 7 km of acacia saplings grown near Bzenec in Moravia, fixed with 5,162 kg of steel, 3,000 bolts and 6,000 nuts. Four cranes assembled it, and in 2018 it received one of five main prizes in the 25th Grand Prix architektů, the national architecture award.
