The Manacles (Cornish : Meyn Eglos, meaning church stones) (grid reference SW820205 ) are a set of treacherous rocks off The Lizard peninsula in Cornwall. The rocks are rich in marine wildlife and they are a popular spot for diving due to the many shipwrecks. Traditionally pronounced mean-a'klz (1808), the name derives from the Cornish meyn eglos (church stones), the top of St Keverne church spire being visible from the area.
The rocks are in Falmouth Bay and extends about 1 nautical mile east and south-east of Manacle Point, on the east coast of the Lizard Peninsula. The nearest village is Porthoustock. [1] The reef consists of many submerged rocks and several groups of rocks that break the surface, although some only do so at low water. The Middle Manacles in the north consist of Maen Chynoweth or Morah (Cornish : Morhogh, meaning dolphin), Chyronos, Maen Gerrick and the Gwinges, the eastern group has Vase Rock and Pen Vin, the large group in the centre include the Minstrel Rock, Carn-dhu, Maen Voes (the Voices) and the Quants and Maen Land is in the south-west.
The Manacles Marine Conservation Zone was designated on 21 November 2013 and covers an area of approximately 3.5km2. The MCZ extends from Porthoustock Point south to Polcries and extends 2 km from the coastline. The seabed varies within the site and includes rocky reefs, vertical rock faces, subtidal sand and intertidal coarse sediment. The sediments in shallow water support Maerl beds. Maerl is a collective term for several species of red seaweed which have a hard, chalky skeleton. It can be an important habitat for juvenile animals, anemones, sea cucumbers and sea urchins.
There have been over a thousand lives lost from more than one hundred ships that have been wrecked on The Manacles. The reef lying on the eastern approach to the port of Falmouth is one reason for the large number of wrecks, although some ships such as SS Mohegan were many miles off course when they ploughed into the rocks. [2]
Many of the well-known wrecks are in the central group where depths are less than 6 metres (20 ft) for an area of 300 by 200 metres (980 by 660 ft). These wrecks include:
In 1885 Trinity House was petitioned for a lightship to be moored near the rocks. Over the previous ten years, sixteen vessels, with 693 crew and passengers had been wrecked and the value of the ships and their cargoes was estimated to be about £100,000. [4]
The Lizard is a peninsula in southern Cornwall, England, United Kingdom. The most southerly point of the British mainland is near Lizard Point at SW 701115; Lizard village, also known as The Lizard, is the most southerly on the British mainland, and is in the civil parish of Landewednack, the most southerly parish. The valleys of the River Helford and Loe Pool form the northern boundary, with the rest of the peninsula surrounded by sea. The area measures about 14 by 14 miles. The Lizard is one of England's natural regions and has been designated as a National Character Area 157 by Natural England. The peninsula is known for its geology and for its rare plants and lies within the Cornwall Area of Outstanding Natural Beauty (AONB).
The Longships is the name given to a group of rocky islets situated approximately 11⁄4 miles (2 km) west of Land's End, Cornwall, England, United Kingdom. The islets are marked by the Longships Lighthouse, the current structure being first lit in December 1873. The islets are very popular for recreational diving, the sea has clear water with prolific marine life and flora.
Coverack is a coastal village and fishing port in Cornwall, UK. It lies in the parish of St Keverne, on the east side of the Lizard peninsula about nine miles (14 km) south of Falmouth.
The Seven Stones reef is a rocky reef nearly 15 miles (24 km) west of Land's End, Cornwall and 7 miles (11 km) east-northeast of the Isles of Scilly. The reef consists of two groups of rocks and is nearly 2 miles (3.2 km) long and 1 mile (1.6 km) in breadth. They rise out of deep water and are a navigational hazard for shipping with 71 named wrecks and an estimated 200 shipwrecks overall. The most infamous is the Torrey Canyon in 1967, which was at that time the world's costliest shipping disaster, and to date, still the worst oil spill on the coast of the United Kingdom.
Porthoustock is a hamlet near St Keverne in Cornwall, England, United Kingdom, on the east coast of Lizard Peninsula. Aggregates are quarried nearby and Porthoustock beach is dominated by a large concrete stone silo that was once used to store stone ready to load ships but is now disused. Coastal trading ships of up to 82 metres can dock alongside the pier along the southern edge of the beach to be loaded with stone. Fishing boats operate from the pebble beach, with lobster and crab potting, net fishing and hand lines as the principal fishing methods. The South West Coast Path passes through Porthoustock.
The SS Mohegan was a steamer which sank off the coast of the Lizard Peninsula, Cornwall, on her second voyage. She hit The Manacles on 14 October 1898 with the loss of 106 out of 197 on board.
HMS Primrose was a Royal Navy Cruizer-class brig-sloop built by Thomas Nickells, at Fowey and launched in 1807.

One road runs through the village, and there is public house, the Five Pilchards, named for the pilchard fishery. Porthallow is at the midpoint of the South West Coast Path and is within the Cornwall Area of Outstanding Natural Beauty (AONB).
Long Reef is a prominent headland on the Northern Beaches of Sydney, Australia. Connected to the mainland by a tombolo, the reef has an extensive wave-cut platform. Long Reef is a popular recreational destination and is one of the more interesting geological areas in Sydney.
The following index is provided as an overview of and topical guide to Wikipedia's articles on recreational dive sites. The level of coverage may vary:
Recreational dive sites are specific places that recreational scuba divers go to enjoy the underwater environment or for training purposes. They include technical diving sites beyond the range generally accepted for recreational diving. In this context all diving done for recreational purposes is included. Professional diving tends to be done where the job is, and with the exception of diver training and leading groups of recreational divers, does not generally occur at specific sites chosen for their easy access, pleasant conditions or interesting features.
