The Great Ocean Road is an Australian National Heritage-listed 240-kilometre (150 mi) stretch of road along the south-eastern coast of Australia, between the Victorian towns of Torquay and Allansford. Built by returned soldiers between 1919 and 1932, and dedicated to soldiers killed during World War I, the road is the world's largest war memorial. Winding through varying terrain along the coast, and providing access to several prominent landmarks, including the Twelve Apostles limestone stack formations, the road is an important tourist attraction.
A natural arch, natural bridge, or rock arch is a natural landform where an arch has formed with an opening underneath. Natural arches commonly form where inland cliffs, coastal cliffs, fins or stacks are subject to erosion from the sea, rivers or weathering.
The Port Campbell National Park is a national park in the south-western district of Victoria, Australia. The 1,750-hectare (4,300-acre) national park is situated approximately 190 kilometres (120 mi) south-west of Melbourne and approximately 10 kilometres (6.2 mi) east of Warrnambool. The park is located adjacent to the Great Otway National Park and the Bay of Islands Coastal Park.
London Bridge is an offshore natural arch in the Port Campbell National Park, Australia. The arch is a significant tourist attraction along the Great Ocean Road near Port Campbell in Victoria. This stack was formed by a gradual process of erosion, and until 1990 formed a complete double-span natural bridge.
The Twelve Apostles are a collection of limestone stacks off the shore of Port Campbell National Park, by the Great Ocean Road in Victoria, Australia. The Twelve Apostles are located on the traditional lands of the Eastern Maar peoples.
Cheddar Gorge is a limestone gorge in the Mendip Hills, near the village of Cheddar, Somerset, England. The gorge is the site of the Cheddar show caves, where Britain's oldest complete human skeleton, Cheddar Man, estimated to be 9,000 years old, was found in 1903. Older remains from the Upper Late Palaeolithic era have been found. The caves, produced by the activity of an underground river, contain stalactites and stalagmites. The gorge is part of a Site of Special Scientific Interest called Cheddar Complex.
In geography and geology, a cliff is an area of rock which has a general angle defined by the vertical, or nearly vertical. Cliffs are formed by the processes of weathering and erosion, with the effect of gravity. Cliffs are common on coasts, in mountainous areas, escarpments and along rivers. Cliffs are usually composed of rock that is resistant to weathering and erosion. The sedimentary rocks that are most likely to form cliffs include sandstone, limestone, chalk, and dolomite. Igneous rocks such as granite and basalt also often form cliffs.
A stack or sea stack is a geological landform consisting of a steep and often vertical column or columns of rock in the sea near a coast, formed by wave erosion. Stacks are formed over time by wind and water, processes of coastal geomorphology. They are formed when part of a headland is eroded by hydraulic action, which is the force of the sea or water crashing against the rock. The force of the water weakens cracks in the headland, causing them to later collapse, forming free-standing stacks and even a small island. Without the constant presence of water, stacks also form when a natural arch collapses under gravity, due to sub-aerial processes like wind erosion. Erosion causes the arch to collapse, leaving the pillar of hard rock standing away from the coast—the stack. Eventually, erosion will cause the stack to collapse, leaving a stump. Stacks can provide important nesting locations for seabirds, and many are popular for rock climbing.
Durdle Door is a natural limestone arch on the Jurassic Coast near Lulworth in Dorset, England. It is privately owned by the Weld Family who own the Lulworth Estate, but it is also open to the public.
The Cliffs of Moher are sea cliffs located at the southwestern edge of the Burren region in County Clare, Ireland. They run for about 14 kilometres. At their southern end, they rise 120 metres (390 ft) above the Atlantic Ocean at Hag's Head, and, 8 kilometres to the north, they reach their maximum height of 214 metres (702 ft) just north of O'Brien's Tower, a round stone tower near the midpoint of the cliffs, built in 1835 by Sir Cornelius O'Brien, then continue at lower heights. The closest settlements are the villages of Liscannor 6 km to the south, and Doolin 7 km to the north.
Pembrokeshire Coast National Park is a national park along the Pembrokeshire coast in west Wales.
Percé Rock is a huge sheer rock formation in the Gulf of Saint Lawrence on the tip of the Gaspé Peninsula in Québec, Canada, off Percé Bay. Percé Rock appears from a distance like a ship under sail. It is one of the world's largest natural arches located in water and is considered a geologically and historically rich natural icon of Quebec. It is a major attraction in the Gaspésie region.
The Gibson Steps are an area of cliffs on the south coast of Australia, located at 38°40′06″S143°06′43″E. The cliffs are the first sightseeing stopoff in Port Campbell National Park for travellers heading West along the Great Ocean Road, located about 2 minutes drive from The Twelve Apostles. The name Gibson Steps refers to the staircase leading down to the stretch of beach shown to the right.
The Loch Ard Gorge is part of Port Campbell National Park, Victoria, Australia, about three minutes' drive west of The Twelve Apostles.
Loch Ard was an iron-hulled clipper ship that was built in Scotland in 1873 and wrecked on the Shipwreck Coast of Victoria, Australia in 1878.
The A2 is a major road in Northern Ireland, a considerable length of which is often referred to the Antrim Coast Road because much of it follows the scenic coastline of County Antrim; other parts of the road follow the coasts in Counties Down and Londonderry.
The Grotto is a sinkhole geological formation and tourist attraction, found on the Great Ocean Road outside Port Campbell in Victoria, Australia. Wooden steps wind down the cliff face to the bottom, providing visibility of the sea beyond a pool at low tide.
Carboniferous Limestone is a collective term for the succession of limestones occurring widely throughout Great Britain and Ireland that were deposited during the Dinantian Epoch of the Carboniferous Period. These rocks formed between 363 and 325 million years ago. Within England and Wales, the entire limestone succession, which includes subordinate mudstones and some thin sandstones, is known as the Carboniferous Limestone Supergroup.
The Azure Window, also known as the Dwejra Window, was a 28-metre-tall (92 ft) natural arch on the island of Gozo, located just off the shores of Malta. The limestone feature, which was in Dwejra Bay close to the Inland Sea and Fungus Rock, was one of the island's major tourist attractions until it collapsed in stormy weather on 8 March 2017. The arch, together with other natural features in the area, has appeared in a number of international films and media productions.
A cliffed coast, also called an abrasion coast, is a form of coast where the action of marine waves has formed steep cliffs that may or may not be precipitous. It contrasts with a flat or alluvial coast.
