Rozhledna Závist, Wooden observation tower near Lhota, Czech Republic

Rozhledna Závist is a 32-metre wooden tower on Hradiště Závist, built in 2021 to a design by Martin Rajniš's studio. Three larch posts with a triangular footprint enclose a circular staircase leading to a viewing platform 24 metres up, which holds almost 30 people. Steel cables anchor the structure to the ground.

The tower, completed in December 2021, was built as the first stage of the Závist–Zpřístupnění project, devised to present archaeological research on Hradiště Závist to the public. That hilltop holds the largest Celtic oppidum in central Bohemia, and the project, with a study by architect Josef Pleskot, also plans coloured concrete slabs marking the buried ground plans of early La Tène buildings.

The tower is the first stage of the Závist–Zpřístupnění project, whose study was drawn up by architect Josef Pleskot to present local archaeological research to the public. A planned mobile application, under the heading of virtual archaeology, is to show the oppidum acropolis as it looked in different phases of its development.

The tower is accessible year-round via marked hiking trails that connect with the local network of outdoor paths in the area. Visitors should wear sturdy footwear, as trail conditions vary depending on the season and weather.

Opponents argued the tower does not belong on a Celtic oppidum and that its height markedly exceeds the surrounding trees, a point raised by Seznam Zprávy. The wider Závist–Zpřístupnění project, studied by architect Josef Pleskot, plans large concrete slabs tinted red, blue-violet, yellow, turquoise, dark green and black on the hilltop beside the tower, recalling buildings uncovered in excavations.
