Říční lázně Polanka, Swimming center in Podklásteří, Czech Republic

Říční lázně Polanka is a wooden river bathing complex in Podklásteří, built in 1933–1934 to a design by Bohuslav Fuchs. The L-shaped timber-frame building has two floors, an open gallery with four staircases, and about 160 changing cabins under a gently sloping galvanized-metal roof. The site also includes a 50-metre pool, a diving pool with a 5-metre tower, a toboggan, and sports courts.

A first bathing place opened on the right bank of the Jihlava around 1910. The wooden river baths, designed by Bohuslav Fuchs, were built in 1933–1934 and opened on 27 May 1934 with a capacity of 1,200 people. A wooden bridge with a diving tower linked them to Polanka; after World War II it was replaced by a Bailey bridge.

The bathing site takes its name from Polanka, the locality along the Jihlava River, and has served as a gathering place for visitors from the surrounding region. The wooden structure and its colored elements have become part of how locals and travelers experience this corner of the landscape.

The historic wooden changing building stands on the Podklásteří bank, while the heated pools, toboggan and sauna lie on the opposite bank; a footbridge over the Jihlava links the two. The pools are a summer operation, so check opening times before travelling. The 50-metre pool has been sinking on one side and losing water through its aluminium shell.

The current yellow, red and blue paint is not the original scheme: the baths were long painted brown, and the first colours of the changing cabins are unknown. Yellow marks the load-bearing timber, red the roof boarding and railing infill, blue the walls and doors.
