The Kurhaus is the spa house in Wiesbaden, the capital of Hesse, Germany. It serves as the city's convention centre, and the social center of the spa town. In addition to a large and a smaller hall, it houses a restaurant and the Wiesbaden Casino, or Spielbank, which is notable for allowing the "highest roulette stakes in Germany", and where Fyodor Dostoyevsky was said to have received the inspiration for his novel The Gambler.
