[1] Lunna Dolina (Moon Valley) is located in Ribartsi, within the Sredno Selo area of the Balkan Mountains.
During the Second Bulgarian Empire when nearby Veliko Tarnovo was the capital of Bulgaria, Moon Valley may have been the summer residence of the ruling tsars.
Three ancient settlements as well eight tombs from the 6th-7th millennium BC have been discovered in the vicinity, and fortress remains have been found in the Gradishte area of the municipality.
In the village of Gorsko Novo Selo a medieval church of 13th-14th century has been discovered, in addition to collections of coins reaching from the time from John Tzimiskes to Isaac II Angelos.
The municipality is currently in the process of establishing an eco-trail following the town's river through a plethora of beautifully unspoilt natural sights.
