Aladzha Monastery is situated in a beautiful area 14 km north of Varna, near Zlatni Pyasatsi Resort (Golden Sands Resort), in the centre of Zlatni Pyasatsi Nature Park (Golden Sands Nature Park). There are no reliable historical records as to when the monastery was established, but there is evidence that it already existed in the 10th – 12th centuries
Aladzha Monastery is one of the few cave monasteries in Bulgaria where the different premises and their functions are clearly distinguishable. The monastery premises are carved and arranged on two levels in a limestone rock that is almost 40 m high. The monastery church, the monastery cells, the refectory, the kitchen, the small cemetery church, the crypt (ossuary), and the farm premises are all situated on the first level. The second level is a natural rock recess in the eastern part of which lies the monastery chapel.
A group of caves known as the Catacombs is located about 600 – 700 m to the west of the monastery. The archaeological finds such as pottery, coins, graffiti, etc., discovered there provide evidence that the Catacombs were inhabited by people during the early-Christian Age (5th – 6th centuries).
