Expert Guide to Identifying Beach Rocks

For centuries, lighthouses played a vital role in maritime navigation, guiding ships through darkness, storms, and hazardous waters. Long before GPS, radar, and satellite navigation, these towering beacons served as lifelines for sailors, helping them avoid reefs, rocky shores, and other dangers at sea.

Lighthouse keepers carefully maintained the lights and signals, ensuring vessels could travel safely along busy shipping routes. Although modern technology has replaced much of their original function, many historic lighthouses remain standing today. Beyond their maritime heritage, they have become beloved landmarks celebrated for their architecture, history, and breathtaking coastal settings.

1. Eldred Rock Lighthouse, Alaska, USA

Positioned on a small rocky island in Lynn Canal near Haines, Alaska, the Eldred Rock Lighthouse is one of the state's most historic navigational structures. Construction began in 1902 and was completed in 1905 following a series of tragic shipwrecks in the surrounding waters. The lighthouse officially entered service in 1906 and remained active until 1973.

Its distinctive octagonal design and dramatic mountain scenery make it one of the most visually striking lighthouses in North America. As Alaska’s oldest surviving original lighthouse, it continues to attract preservation efforts led by local organizations dedicated to maintaining this important piece of maritime history.

2. Tower of Hercules, Spain

Standing at the entrance to the harbor of La Coruña in Galicia, the Tower of Hercules is one of the world's oldest operating lighthouses. Dating back to the late first century AD, it remains the only Roman lighthouse still functioning for maritime navigation.

Built atop a rocky headland overlooking the Atlantic Ocean, the structure rises prominently above the coastline. Extensive renovations during the 18th century helped preserve the tower while maintaining its original purpose. Today, the lighthouse is recognized as a UNESCO World Heritage Site and welcomes visitors throughout the year.

3. Les Eclaireurs Lighthouse, Argentina

Situated in the Beagle Channel near the city of Ushuaia, Les Eclaireurs Lighthouse occupies one of the southernmost locations on Earth. Often referred to as the “Lighthouse at the End of the World,” it stands on a small island surrounded by the rugged landscapes of Tierra del Fuego.

Commissioned in 1920, the lighthouse features distinctive red-and-white stripes that make it easily recognizable from passing vessels. While the structure operates automatically and is not open to visitors, it can be viewed during boat excursions through the channel, where snow-capped mountains create a spectacular backdrop.

4. Tourlitis Lighthouse, Greece

Off the coast of Andros Island in the Aegean Sea stands one of the most unusual lighthouses in the world. Tourlitis Lighthouse sits atop a narrow rock pillar sculpted by centuries of erosion, creating the appearance of a structure lifted straight from a fantasy novel.

Originally completed in 1897, the lighthouse was destroyed during World War II and later rebuilt in the 1990s. A stone staircase carved into the rock leads toward the structure, enhancing its dramatic appearance. Following its reconstruction, Tourlitis became Greece’s first fully automated lighthouse.

5. Pigeon Point Lighthouse, California, USA

Located about 50 miles south of San Francisco, Pigeon Point Lighthouse ranks among the tallest lighthouses in the United States. Rising 115 feet above the Pacific coastline, the tower first illuminated the surrounding waters in 1872.

Despite modernization over the years, it remains an active aid to navigation managed by the U.S. Coast Guard. The surrounding area is now part of a state historic park, and visitors can stay nearby while enjoying panoramic views of the rugged California coastline.

6. Whiteford Point Lighthouse, Wales

Off the Gower Peninsula in Wales stands Whiteford Point Lighthouse, a truly unique structure. Constructed in 1865, it is the only cast-iron lighthouse in Britain that becomes completely surrounded by seawater during high tide.

The lighthouse guided ships through the shallow waters around Whiteford Point until 1926. Remarkably, despite being used as a bombing target during World War II training exercises, the structure survived. Visitors can approach it on foot during low tide, though caution is required due to unstable mudflats and rapidly changing water levels.

7. Earhart Light, Howland Island

Located on remote Howland Island in the Pacific Ocean, Earhart Light stands in one of the most isolated locations on Earth. The tiny island lies roughly midway between Hawaii and Australia and is best known for its connection to aviator Amelia Earhart.

A runway was built there in 1937 as a planned refueling stop during Earhart’s around-the-world flight, though she never reached the island. The lighthouse suffered damage during World War II but was rebuilt during the 1960s. Today, it functions as a daytime navigational marker, though its condition has deteriorated significantly. Access to the island is strictly controlled due to its protected status as a wildlife refuge.

8. Chania Lighthouse, Crete, Greece

Guarding the entrance to the historic harbor of Chania on the island of Crete, this lighthouse is among the Mediterranean’s most recognizable landmarks. The original structure dates back to the 16th century, though only its foundation remains from that period.

During the early 19th century, the lighthouse underwent extensive reconstruction and adopted its distinctive minaret-like appearance. Because the renovation occurred while Egyptian forces occupied Crete, the lighthouse became associated with Egyptian architectural influences. Although visitors cannot enter the tower, the harbor promenade provides excellent views of both the lighthouse and the surrounding sea.

9. Portland Head Light, Maine, USA

Located on the rocky shores of Cape Elizabeth, Portland Head Light is one of Maine’s most treasured landmarks. The lighthouse first began operating in January 1791, making it one of the oldest surviving lighthouses in New England.

Automation eventually replaced resident keepers in 1989, but the lighthouse remains active today. The former keeper’s residence has been transformed into a museum showcasing navigational equipment, historic lenses, and exhibits exploring the region’s maritime past. Visitors who reach the site are rewarded with sweeping views of Maine’s rugged coastline and the Atlantic Ocean.

Preserving Maritime Heritage

Although modern navigation systems have largely replaced traditional lighthouse operations, these historic structures continue to serve as powerful symbols of maritime history. From remote Alaskan islands and windswept Welsh shores to ancient Roman towers and dramatic Greek sea stacks, each lighthouse tells a unique story of exploration, engineering, and life at sea. Today, they remain among the world's most captivating coastal landmarks, attracting travelers who come not only for the scenery but also to connect with centuries of seafaring heritage.
