Sveti Andrija Lighthouse (Croatian: Svjetionik Sveti Andrija) is located on the island of Sveti Andrija, off Lopud Island in the Elaphiti archipelago. The nearest settlement is Lopud, Dubrovnik Municipality, Dubrovnik-Neretva County, Croatia. The lighthouse's official website is https://www.plovput.hr/pomorska-signalizacija/svjetionici/svjetionik/a/view/id/11.

Construction and History

The construction of the Sveti Andrija Lighthouse began in 1873 under Austro-Hungarian maritime authorities. The lighthouse was first lit in 1877, although this date is speculative based on regional patterns. Its purpose was to guide vessels through the passage between Lopud and the mainland, mark a hazardous rocky islet, and warn of potential shipwrecks.

Architecture and Materials

The Sveti Andrija Lighthouse is a cylindrical, conical-tapered tower attached to a single-storey keeper's house. The tower is made of local limestone masonry, with an iron lantern room and a red-tiled roof on the keeper's quarters. The exterior is painted white, with a lantern gallery and dome in red.

Light and Navigation

The lighthouse has a tower height of 17 meters above base to lantern roof and a focal height of 55 meters above mean sea level. Its light range is approximately 33 kilometers. The characteristic is group flashing – three white flashes every 15 seconds (Fl (3) W 15 s). The optic and lamp are modern, with a rotating beacon replacing the original dioptric lens.

Accessibility and Visiting

The Sveti Andrija Lighthouse is not easily accessible to the general public. There is no regular ferry service to the island, and access is only possible by private boat or charter from Lopud/Dubrovnik. The interior of the lighthouse is closed to visitors, but the exterior can be visited with prior permission from Plovput.

Notable Views and Landscape

The Sveti Andrija Lighthouse sits on a rocky islet rising steeply from the Adriatic Sea, surrounded by sparse Mediterranean shrubland. From the lantern gallery, one can enjoy panoramic vistas of the Elaphiti Islands, Old Town of Dubrovnik, and Pelješac Peninsula.

Anecdotes and Folklore

In the past, keepers would serve tours of duty lasting up to four months, weather-bound in winter. Local boatmen have claimed to glimpse a "ghost light" on stormy nights near the rocks before the lighthouse was built. The islet's surrounding reefs accounted for several 18th- and 19th-century grounding incidents, prompting the construction of the Sveti Andrija Lighthouse.

Technical and Operational Details

The Sveti Andrija Lighthouse has been fully automated since the late 20th century and is unmanned. The power supply is grid-connected with battery backup (recent photovoltaics installation). There is no AIS transponder on site, but a radar reflector was installed on the lantern.
