Aladja is the best known medieval rock monastery on the Bulgarian Black sea coast located at some 14 km North-East from Varna and about 3.5 km west of Golden Sands resort. It is declared a protected historical site. Today, one can see some rooms, monk’s cells and a chapel, which are embedded into the rocks at a height of 20 metres. The chapel still keeps some medieval murals of the 14th century.
The monastery was founded in the 13th century in rock caves, which had been used before – as early as the 4th – 6th centuries – by hermits and brotherhoods of monks. It was inhabited until the 18th century. There is also a small museum with an ehibition hall. Models, sketches and photographs related to the history of the monastery can be seen there. Also there is a permanent exhibition of copies of medieval murals of 12th – 16th centuries.
