The square is located in the historical centre of Tusnádfürdő and forms the southern end of the spa town's pedestrian street. The square is defined by the facades of three buildings, one of which, also known as canteen No. 4., serves as the location of the baths. It was built in the 1950s on the remaining andesite cellar of the erstwhile grand medicinal hall, which was originally constructed in 1890 and burned down in 1914. The bathing process in the spa takes human physiology into account. It begins with a lukewarm bath, followed by a session of hotter water and then returning to lukewarm water again. It is then followed by a cold bath, and finally, to normalise the circulatory system after the temperature variations, it concludes with a period of rest. The building of the spa complements and integrates with the built and natural environment surrounding it. The spa building maintains the material continuity of the mountainside. Beneath the surface, artificially shaped spaces are carved out of the mountain itself. On the surface, alongside the living trees of the forest areas, it incorporates man-made wooden structures into the sequence of tree-filled spaces that stretch along the valleyside. The two main levels of the spa cater to two different bathing attitudes. The lower level provides a tranquil and immersive bathing experience, while the open spaces on the surface offer a 'louder', more dynamic, and livelier atmosphere. The temperature of the pools varies with the location. On the ground floor level, there are cold-water pools; half a level below, the water is lukewarm, and the hot pool is located at the deepest level.
