The complex of this thermal swimming area is an organically formed work of mature Functionalist architecture, with great sensitivity to the natural surroundings – one of the architect’s best achievements. It was constructed in the late 1930s, during the greatest flourishing of the thermal spa of Trenčianske Teplice, on a south-facing slope above the spa area, with thermal water piped upwards from the valley. Construction was divided into three stages. Building I contained all of the main operational spaces, including a pool of 33.3 x 12 m. Building II was a bowling alley, and III a children’s area with a shallow circular pool. In the design, Fuchs devoted great attention to the enrichment of his previously highly austere Functionalist forms, and used pure, artistically refined means to create a work of functional clarity that fitted organically into the surroundings. The rich colours and range of materials emphasises the architectural richness of the baths; the structural framing is subtle yet also fully load-bearing. The ‘Green Frog’ is one of the great works of late Czechoslovak functionalism, and was regarded by the architect as one of his two personal favourites.
