Bathhouse Row

Bathhouse Row is a collection of bathhouses, associated buildings, and gardens located at Hot Springs National Park in the city of Hot Springs, Arkansas. The bathhouses were included in 1832 when the Federal Government took over four parcels of land to preserve 47 natural hot springs, their mineral waters which lack the sulphur odor of most hot springs, and their area of origin on the lower slopes of Hot Springs Mountain.The existing bathhouses are the third and fourth generations of bathhouses along Hot Springs Creek, and some were built directly over the hot springs. Because of this resource, the area was set aside in 1832 as the first federal reserve.
