The hermitage holds an astronomical telescope with a lens diameter of 175mm, considered one of the largest in Southeast Europe during the 1920s.
The last hermit, Father Niko Miličević, was an amateur astronomer who discovered several asteroids and corresponded with international observatories.
The library includes preserved medical records and early pharmacy equipment used by the monks.
Construction utilized the natural cave wall as the rear boundary for many of the residential chambers.
The monastery was never connected to the electrical grid, relying on solar power and manual labor until its final days.
The monks produced 'Blaca wine' and honey, which they traded with mainland merchants.
Blaca Hermitage is a remote monastery built directly into the side of a steep limestone cliff on the island of Brač, Croatia. Originally established in the 16th century by Glagolitic monks fleeing Ottoman advances, the site evolved into a significant astronomical and cultural center. The facility houses a library with over 11,000 books, including several rare Glagolitic manuscripts. A notable feature is the 19th-century telescope, one of the most powerful instruments in the region at the time. The monks maintained an self-sufficient lifestyle, managing nearby vineyards and honey production. The site is accessible only by a rugged hiking trail through a canyon. It currently serves as a museum managed by the Center for Culture Brač. The architecture integrates natural cave structures with stone-built additions.

Wear sturdy, closed-toe hiking shoes as the access path is rocky and uneven.
Carry plenty of drinking water, as there are no amenities or shops once you begin the trek.
Check local weather reports; the canyon can become extremely hot in midday summer sun.
Do not attempt the hike in flip-flops or open sandals, as the limestone terrain is sharp and treacherous.
Closed on Mondays; operations often limited to seasonal months from spring through autumn.
Maintain a quiet tone, as the interior spaces are small and echo easily.
