It is the only known nesting site globally where white storks (Ciconia ciconia) build nests on isolated maritime rock pinnacles.
The lighthouse was inaugurated in 1915 to bridge the gap between the lighthouses at Cabo de São Vicente and Cabo Espichel.
The light characteristic is a group of three flashes every 15 seconds, visible from 22 nautical miles away.
The structure sits atop cliffs composed of metamorphic schist and greywacke dating back to the Carboniferous period.
The primary Fresnel lens used in the lighthouse has been replaced with modern LED-based optical systems.
The nesting site has been monitored by ornithologists since the 1980s due to the unique adaptation of the storks to the salt-spray environment.
Farol do Cabo Sardão is an active lighthouse situated on a rugged cliffside along the Alentejo coastline within the Southwest Alentejo and Vicentine Coast Natural Park. The lighthouse tower stands 17 meters tall and features a white cylindrical structure with a red lantern room. It marks a critical navigational point on the Portuguese Atlantic coast where the shoreline turns sharply. The site is notable for being the only place in the world where white storks build their nests on the precarious sea stacks and cliff ledges rather than trees or rooftops. Visitors can observe these protected birds up close as they raise their chicks above the crashing Atlantic surf. The surrounding area consists of protected coastal trails that are part of the Rota Vicentina hiking network. The lighthouse remains fully operational and is managed by the Portuguese Maritime Authority.

Bring high-quality binoculars to view the stork nests on the sea stacks safely without disturbing the birds.
Wear sturdy hiking boots if you plan to walk the surrounding coastal cliff paths.
Check local wind forecasts, as the cliff-top exposure makes the area significantly colder and windier than inland locations.
Attempting to climb down the cliffs to reach the water, as the schist rock is highly unstable and prone to landslides.
The lighthouse tower is generally closed to public interior tours; access is limited to the exterior grounds.
Maintain a quiet distance from cliff edges and nesting sites; do not attempt to feed or approach the storks.
