Abyanah is a small village close to Natanz, located in the mountain valley of Barz-Rud. The village is known for its vernacular architecture and customs. Its architecture developed to suit the steeply sloping ground on which the village is built: houses are built close to one another on terraces and consist of several stories. They overlook the valley below through latticed windows. Wood is used extensively, and the city's congregational mosque is known for its wooden ceilings and furniture.
