By Perched dramatically on the rugged coastline of Llanddwyn Island in Anglesey, Twr Mawr Lighthouse is one of the most iconic maritime structures in Wales. With its distinct whitewashed tower, panoramic sea views, and mythic Welsh heritage, Twr Mawr draws thousands of visitors each year. More than a navigational aid, this lighthouse represents a perfect confluence of natural beauty, maritime tradition, and cultural significance.
This article provides a comprehensive look at Twr Mawr Lighthouse, its history, how to visit it, what makes it unique, and why it holds a special place in Wales’ coastal narrative.
The Origin and History of Twr Mawr Lighthouse
Built in 1845, Twr Mawr (Welsh for “big tower”) was designed to guide ships through the Menai Strait — a narrow and hazardous waterway separating Anglesey from mainland Wales. It replaced a smaller, less effective beacon known as Twr Bach (“little tower”), which had been in use since the early 1800s.
Though it may resemble a windmill due to its tapered shape and lack of lantern gallery, Twr Mawr functioned efficiently as a daytime navigation point. It originally used an oil lamp and later benefited from modest technological upgrades before being decommissioned in favor of more modern lighting systems.
Today, while no longer operational as a lighthouse, Twr Mawr remains a beloved architectural relic, blending effortlessly into the windswept landscape of Llanddwyn.
Architectural Features and Design
Twr Mawr Lighthouse stands about 11 meters (36 feet) tall, constructed primarily of limestone. Its base is broad and conical, tapering gracefully toward a domed cap. The whitewashed walls, often catching the golden light of sunset, make it a photographer’s dream.
While it lacks the traditional lantern room and balcony of most lighthouses, its unique silhouette and coastal setting have made it instantly recognizable. Twr Mawr’s design also reflects local building traditions and aligns harmoniously with the surrounding ruins and chapels on the island.
Location: Llanddwyn Island, Anglesey
Twr Mawr Lighthouse is located on Llanddwyn Island, a tidal island off the southwest coast of Anglesey. The island itself is part of the Newborough Warren National Nature Reserve, offering unspoiled beaches, rolling dunes, and pine forests.
Though technically an island, Llanddwyn is accessible on foot during low tide, making it a popular walking destination. From the mainland, the lighthouse is about a 45-minute walk along the sandy shoreline or forest trails, depending on the chosen route.
Myth and Legend: Saint Dwynwen and the Island’s Spiritual Heritage
One of the reasons Twr Mawr Lighthouse feels so enchanting is its connection to Welsh mythology. The island is named after Saint Dwynwen, the patron saint of lovers in Wales. Her chapel ruins remain a significant pilgrimage site, particularly on January 25th, which is St. Dwynwen’s Day.
Many visitors come to the island not only to see the lighthouse but to soak in its deeply spiritual and romantic atmosphere. It is said that the island’s tranquility has healing powers, and many come seeking inspiration, peace, and connection.
