World culture heritage, national 4A scenic spot, major historical and cultural site under state protection. This scenic spot lies in Xiandu Town of Hua’an County, and is constituted of three Tulou--Eryi Lou, Nanyang Lou and Dongyang Lou. The name of Eryi Lou bears the implication that it is a worthy place of both mountains and waters, both home and family, and both indoor and outdoor life. Eryi Lou is regarded as “King of Tulou” because its scientific design and unique construction have been well preserved. Built in 1770 AD, this round Tulou is 73.4 meters in diameter and covers an area of about 6700 square meters. Eryi Lou is not only comfortably surrounded by mountains and streams; it also has exquisite interior decorations including fine cravings in wood, in stone, and in bright-colored mural paintings.
