Green Bridge of Wales, Natural arch in Pembrokeshire, Wales.
The Green Bridge of Wales rises 24 meters above the sea with a span of 20 meters, featuring a limestone structure covered with vegetation.
The natural arch developed through centuries of coastal erosion, with waves carving caves into the carboniferous limestone until they connected to form the bridge.
The site holds protected status as a Site of Special Scientific Interest, Special Protected Area, and Special Area of Conservation for its geological importance.
Access to the Green Bridge requires visitors to check the status of the Castlemartin military range, as the road passes through an active training area.
Hurricane Ophelia in 2017 caused substantial stone loss from the outer arch, accelerating the natural process toward its eventual transformation into a sea stack.
