The first hamams (Turkish baths) were heated internally via a pipe system built by the Romans. During the Roman period, the baths were used as physical training and therapy centers. When the Turks came to Anatolia, they combined their own bathing traditions with those of Byzantium and Rome, and integrated them with Islamic rules and customs. Since still water is regarded as unclean in the Islamic world, the usage of bath pools or tubs was replaced with running hot water baths, which gave birth to a new bathing culture in Anatolia that was institutionalized as the hamam. The first Turkish bath was built by the Seljuks in Anatolia, but when Mehmet II conquered Constantinople, numerous Byzantine hamams were built. The word hamam is actually a term borrowed from Arabic, which means "to heat" or "to be hot." During the Ottoman era, Turkish baths were built in almost every Ottoman city and were integrated into daily life. The baths were not only a part of culture and tradition, but had a religious aspect as well. According to Islam, cleanliness is an important and essential part of life and religion, and one must clean the body thoroughly before any acts of worship. Aside from cleaning the body, the early hamams were places where people socialized together as well. These social gatherings would occur at almost every occasion, such as before weddings, holidays and while celebrating the birth of a newborn. Turkish coffee and Turkish sweets would also be served. There are many historical hamams in Istanbul worth visting. Some of these hamams are tourist attractions and can come with an extravagant price tag. However, there are also hamams that are historic, beautiful and affordable. Whatever your budget may be, there is a hamam out there for you to enjoy.Fancy and Luxurious HamamsKılıç Ali Pasha Hamam in TophaneThis unique Turkish bath is located in Tophane next to the mosque with the same name.
