The modern hotel complex and spa sanatorium known as the Thermal Hotel was built between 1967 and 1976 according to the design of the Czech husband-and-wife team of architects Věra and Vladimír Machonin. The dominant, high-rise hotel building may boast a convention centre with vast premises suitable for festivals, congresses, symposiums, concerts and many other cultural events. Inseparable from the hotel is its unique open-air heated swimming pool supplied with thermal water from the Hot Spring. Every year, the Thermal Hotel is the central venue of the Karlovy Vary International Film Festival.
