In ancient times Yalova was known as Helenapolis in memory of Emperor Constantines mother Helena who designed the city. Today Yalova is an important port city famous for its thermal baths. Termal in the southwestern part of the city is the center of the thermal district and the best place in Turkey to enjoy the curative thermal bath waters. In Termal theres a wonderful panoramic view of the entire Thermal district center from the top of a hill overlooking the city. The Ataturk Mansion located in Yalova is now a museum -open to the public weekdays except Monday and Thursday-. Built in 1929 Ataturks former summer residence displays original furnishings from the early 20th century. Seventeen km west of Yalova the relaxing resort area of Cinarcik has lovely beaches and modern accomodations.
