Sedlo, Observation tower in Sušice, Czech Republic.

Sedlo is a 27.75 m wooden observation tower on the summit of the 902 m Sedlo hill above Albrechtice u Sušice. Its seven-sided plan tapers upward, with a covered viewing platform at 23.75 m, clad in boards and topped by a diamond-shaped roof. The tower stands on a dark open frame base with diagonal struts.

A military observation post stood on the summit during the Second World War and was used until the 1950s; abandoned, it collapsed. The Sdružení pro obnovu rozhledny na Sedle association pushed for a new tower, built in the second half of 2009, finished on 30 November and opened on 13 December 2009. The town of Sušice has managed it since 2016.

The name Sedlo means "saddle" in Czech, and the hill's German name Hefenstein coexists with the folk name Rittersattel. The wooden tower was funded partly by a public collection in which donors could buy individual steps; their names are displayed on the steps they paid for.

You can visit throughout the year, but be prepared for stairs when heading to the viewing platform. Wear sturdy shoes and expect stronger winds at the top, especially during weather changes.

The tower stands on a prehistoric hillfort site: a 920-metre rampart enclosed an area 400 metres long and 32 to 114 metres wide, with walls up to 13 metres thick and, on the slope side, up to ten metres high. The fortification was used between 470 and 385 BC and again in the 9th and 10th centuries.
