One of the distinctive ancient monuments of Ankara is the Karacabi Historic Bath, which was built by Celalettin Karacabey Ibn-i Abdullah, who was one of the Sultan's soldiers. The historical bathroom, where the past, future, history and modernity merge, is located in a closed area of about two thousand square meters, which includes private spaces for men and women. The marble used in the bathroom floor was brought from the city of Afyonkarahisar, and onyx marble was used in some places. Embroidered almost like lace with great dedication, the hammam houses one of the oldest and most ancient heating systems in the country.
