The eleventh church, Biete Ghiorgis (House of St. George), is isolated from the others, but connected by a system of trenches. Near the churches, the village of Lalibela has two storey round houses, constructed of local red stone, and known as the Lasta Tukuls. AuthenticityThe Rock-Hewn Churches of Lalibela are still preserved in their natural settings. The association of the rock-hewn churches and the traditional vernacular circular houses, in the surrounding area, still demonstrate evidences of the ancient village layout. No special legal framework is provided to protect the Rock-Hewn Churches except the general law, Proclamation No.
