Name and Location

The Grebeni Lighthouse, officially known as Svjetionik Hridi Grebeni, is an active sea-light located on the rocky islet cluster known as Grebeni off the Lapad peninsula of Dubrovnik, Croatia. Its coordinates are 42°39′05.65″ N, 18°02′52.43″ E.

2. Construction and History

The lighthouse was first illuminated in 1872 under Austro-Hungarian administration. It remains in service today under the authority of the Croatian maritime signalization company Plovput. The year it was built is recorded as 1872, and it was constructed by Austro-Hungarian maritime authorities.

3. Architecture and Materials

The lighthouse has a masonry tower structure, rising directly from the rocky ledge. Its shape and marking are likely cylindrical or tapered, painted white with a contrasting lantern. The detailed paint scheme is unrecorded in public sources.

4. Light and Navigation

The light characteristic is not published in readily available sources; mariners should consult current nautical publications or Croatian Notices to Mariners for Fl, Oc or Iso patterns, range, and color. The lighthouse serves as a warning of nearby shoals and is listed in the Aids to Navigation catalogue for the Adriatic Sea.

5. Accessibility and Visiting

The lighthouse is not open to visitors due to its offshore location and lack of landing facilities. It can be approached by private boat or organized tour vessel only; landing is possible on calm days via small craft. There are no on-site facilities beyond basic lighthouse machinery room.

6. Notable Views and Landscape

From the lighthouse, one can enjoy a panoramic vista eastward over Lapad Bay and the hills of Dubrovnik's western suburbs. Westward, there is an open view toward the Elaphiti Islands. The surrounding landscape features rugged karst islets rising from deep blue Adriatic waters, often surrounded by breaking waves.

7. Anecdotes and Folklore

Local fishermen simply refer to the lighthouse as "Grebeni" ("the reefs"). Sailors of old spoke of the "grebeni" as treacherous rocks that once caused minor groundings in stormy weather – hence the need for a robust lighthouse.

8. Technical and Operational Details

The lighthouse is fully automated, with no permanent on-site keepers. Power is supplied via solar panels and battery backup, typical for Plovput-managed aids.
