Name and Location

Agios Georgios Afentis-Cherronisos Lighthouse is a small beacon tower situated on a rocky promontory just off the north-eastern coast of Sifnos Island in the Cyclades, Greece. The lighthouse is located at coordinates 37°02′18.8″ N, 24°38′35.2″ E and can be reached by Plus Code 2JQV+C6 Sifnos, Greece.

Construction and History

The Agios Georgios Afentis-Cherronisos Lighthouse marks the chapel and islet known locally as “Cherronisos” or “Afentini,” named for the nearby church of Agios Georgios (Saint George). The exact construction date is unknown, but it is believed to be a small masonry lighthouse/landmark tower built using local stone and whitewashed masonry.

Architecture and Materials

The lighthouse appears as a simple square or octagonal tower rising adjacent to the chapel of Agios Georgios. It is painted white to stand out against the blue Aegean backdrop, likely standing under 10 meters tall.

Light and Navigation

Unofficially, the lighthouse functions primarily as a daymark rather than a high-power navigational light, with an unknown characteristic and range.

Accessibility and Visiting

The islet and its twin church-lighthouse can be reached on foot at low tide via a narrow rocky causeway from the village of Artemonas or by private boat. There are no visitor facilities on site, but the chapel is occasionally used for religious services.

Notable Views and Landscape

From the tower base and adjacent chapel one enjoys panoramic views across the northern bays of Sifnos, with sightlines to neighboring Cycladic isles (Serifos, Kimolos) and the deep blue Aegean. The rocky shoreline and scrub-covered hills behind lend a quintessential Cyclades character.

Technical and Operational Details

The lighthouse appears to be automated, with no resident keeper, and is likely under the jurisdiction of the Hellenic Navy Hydrographic Service or the Greek Ministry of Shipping. Its current use is as a minor aid to navigation and local landmark, but it is not open for interior visits.
