Blaca Monastery, also known as Pustinja Blaca, is a historical and cultural monument located on the southern coast of Brač Island in Croatia.

The monastery was founded in the 16th century by Glagolitic priests who fled to the island to escape the Ottoman invasion of their homeland. The monks built the monastery in a remote location in a limestone canyon in the northern part of Brač, which provided natural protection from the outside world.

Over the centuries, the monks developed the monastery into a self-sufficient complex that included a church, living quarters, a library, an observatory, and an agricultural estate. The monastery is a fascinating example of human resilience and ingenuity in the face of adversity.

Today, the monastery is open to visitors, who can explore the complex and learn about its history and culture. The area around the monastery is also known for its stunning natural landscapes and hiking trails.
