Aladzha Monastery is a medieval Orthodox Christian cave monastery complex in northeastern Bulgaria, 17 km north of central Varna and 3 km west of Golden Sands beach resort, in a protected forest area adjacent to the Golden Sands Nature Park.
The monastery caves were hewn into a 25-m high vertical karst cliff near the upper edge of the Franga Plateau on several levels. The complex includes two small nearby catacombs.
Dedicated to the Holy Trinity, it was an active hesychast monastic community of the Second Bulgarian Empire since the 12th century and perhaps survived until the early 18th century. Nearby, remains of a 5th-century cave monastery have been found.
A cave monastery may have existed not far from the modern monastery Aladzha, near Varna. Its early dating to the fourth century is secured by fragments of glassware, but coins of Justinian indicate that the complex may have still been in use during the 500s.
Today, the grotto is a popular tourist destination. Its present name appeared in the late Ottoman period; Alaca (Turkish for motley) referred to its colourful murals, now almost destroyed. Thematic light shows are being staged in the summer.

Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
