About this city

Also known as: Home of The Lost Sea

Nestled precisely in the picturesque agricultural rolling valley country of central Monroe County, Sweetwater is a historic town deeply rooted in early East Tennessee railroad expansion. Incorporated in 1875 and named after the natural, sweet-tasting mountain springs discovered by early pioneer scouts, the community originally developed as a prosperous shipping center along the East Tennessee, Virginia and Georgia Railway network, processing vast quantities of wool, dairy, and lumber. Sweetwater achieved international scientific and geological acclaim due to its proximity to 'The Lost Sea,' a rare, massive subterranean cave system that houses the largest underground lake in the United States. Today, the town preserves a charming, historic downtown square filled with Victorian red-brick architecture, balancing its quiet country lifestyle with high-quality eco-tourism.
