Le Pinacle

Les Landes is an area of coastal heathland in the north-west of Jersey. It has been designated as a Site of Special Interest (SSI) since 1996. The site is the largest of its kind in Jersey at 160 ha.

Grosnez Castle is a ruined 14th-century castle in Saint Ouen, situated on the Grosnez headland in the north-west corner of the island of Jersey in the Channel Islands. None of the castle's history was known before the late nineteenth century when archaeological excavations were carried out to remove large quantities of rubble which covered all of the present ruins other than the top of the gatehouse. There are extremely few documentary records relating to the castle and as a result, following the archaeological excavations, various theories were put forward by archaeologists and historians as to the castle's origins and history. Many have been repeated so often in the last ninety years that they have been regarded as the authoritative truth rather than possible theories as originally made. A review and further research of the archaeology and history of the castle have recently been published which puts forward a different and alternative plausible history. That recent research suggests that the castle had an extremely short life immediately before it was captured by the Duc de Bourbon, who had opportunistically invaded the Channel Islands with Bertrand du Guesclin, Marshall of France, in 1373 hoping to capture rich booty and extract tributes and ransoms from islanders. The research suggests that construction of the castle was started by Sir Renaud de Carteret, Seigneur of St. Ouen in about 1369–70 at the time warfare was renewed in the Hundred Years' War following the Treaty of Brétigny of 1360, and it was probably not even complete at the time of its capture three or four years later. Following the common practice of warfare at the time, as there was no intention of occupying it longer term, the Grosnez Castle was sufficiently destroyed by Bourbon and du Guesclin to prevent its reoccupation and use by the inhabitants of Jersey, who would have been required to pay ransoms and tributes to the invaders in future years as agreed, and which the invaders would have little hesitation in brutally enforcing. In the case of De Guesclin and Bourbon, the island paid tributes until the end of 1375.

Lewis Tower (also known as Lewis's Tower) is a Martello tower in St Ouen's Bay on the island of Jersey. It was erected by the British in 1835, and is named after Colonel Griffith Lewis, who commanded the Royal Engineers in Jersey from December 1830 to January 1836.

St Ouen (Jèrriais: Saint Ouën, French: Saint-Ouen) is one of the twelve parishes of Jersey in the Channel Islands. It is around 8.8 kilometres (5.5 mi) north-west of St Helier. It has a population of 4,097. The parish is the largest parish by surface area, covering 8,525 vergées (15 km2), and is located in part on a peninsula. The parish is largely agricultural. There is no single centre, for the church, parish hall, and school are separated; St Ouen's Village is the most significant settlement in the parish. The parish hosts the northernmost section of its namesake bay, which sweeps from the north to the south of the island. It is a distinct parish culturally. Being the farthest from St Helier, it has many differences from the rest of the island, for example having its own dialect of Jèrriais. Its manor, St Ouen's Manor — the seat of the de Carteret family for over eight centuries — is the senior fief in the island, and the influence of that family has also been a factor in the parish's independent-minded approach to its affairs.

Kempt Tower, in La Grande Cueillette, Saint Ouen, Jersey, is also known as Saint Ouen No. 2 and La Grôsse Tou in Jèrriais, and is a Martello tower that the British completed in 1834. It is named for Sir James Kempt, the Master-General of the Ordnance from 1830 to 1834. While governor of Canada, Kempt was involved in the planning for the use of Martello towers to protect the colony. Currently, Kempt Tower serves as the interpretation centre for Les Mielles conservation area.

La Tour Cârrée, or The Square Tower, on Jersey, is not a tower but rather is a fortified guardhouse and magazine in the style of a blockhouse with loopholes for musketry. It may have been erected in 1778 on the site of a redoubt. The tower supported a battery of three 24-pounder cannons that stood on a paved surface in front of it. Shingle now covers this surface. The tower and battery played a role in the repelling in 1779 of the Prince of Nassau's attempt to land a force at the Franco-Dutch Invasion of Jersey. Historically, the structure and redoubts near it have been known as Square Fort, North Battery, and New North Battery. It is located on St Ouen's Bay, by St Ouen's Pond. Today the structure is painted white and black on the seaward side to serve as a daymark for sailors. Since 2007 the tower has been available as self-catering accommodation under a program the Jersey Heritage Trust administers for the States of Jersey Towers and Forts project. Accommodation is extremely basic as the site has no utilities whatsoever.

Grève de Lecq Barracks is an army barracks in Jersey. Construction began in 1810 in response to the threat of invasion by the French. It functioned until 1926 and was acquired by the National Trust for Jersey in 1972. These barracks were unoccupied at the Census of 1921.

British United Airways Flight 1030X crashed on 14 April 1965 on Jersey in the Channel Islands. Poor visibility and low cloud cover resulted in an aborted landing attempt, leading to a second attempt which ended with the Douglas C-47B hitting the outermost pole of the approach lighting system before crashing into a field and catching fire. The crash killed all 23 passengers and three of the crew on board; a flight attendant was the only survivor of the accident.

St Anne's Chapel is a mediaeval chapel within the grounds of St Ouen's Manor, in the parish of St Ouen on Jersey. It is dedicated to St Anne, the mother of the Virgin Mary.

St. Ouen's Manor is a manor house in the parish of St. Ouen, Jersey, and is the traditional home of the Seigneur of St. Ouen, and the ancestral home of the De Carteret family. The earliest record of the house dates from 1135. The manor also includes a mediaeval chapel, St Anne's Chapel. As a part of the 1940 Jersey local elections, the manor was offered to the victor, Edward Campbell. However, Campbell became disillusioned with the idea, and declined. The house and grounds remain intact today, and the house is a private home for the De Carteret family. It is occasionally open to the public.

Les Pierres de Lecq (French pronunciation: [pjɛʁ də lɛk]; Jèrriais: Les Pièrres dé Lé) or the Paternosters are a group of uninhabitable rocks in the Bailiwick of Jersey between Jersey and Sark, 6 km (3.7 mi) north of Grève de Lecq in Saint Mary, and 22.4 km (13.9 mi) west of the Cotentin Peninsula in Normandy. Only three or four of the rocks remain visible at high tide: L'Êtaîthe (the eastern one), La Grôsse (the big one) and La Vouêtaîthe (the western one). The area has one of the greatest tidal ranges in the world, sometimes being as much as 12 m (40 ft). The name Paternosters is connected with a legend relating to the colonisation of Sark in the 16th century. According to this legend a boatload of women and children was wrecked on the reef and their cries can still be heard from time to time in the wind. Superstitious sailors would say the Lord's Prayer when passing the rocks, hence the name Paternosters. The rocks are considered to form a biogeographical boundary between a cold and a warmer part of the ocean. Together with the diverse geology of the area and the differences in wave exposure of the different parts, this creates a diverse range of habitats and considerable biodiversity. The variety of algal assemblages support a range of invertebrate species and provides a nursery area for many fish species. Among the fish for which this area is important are the European sea sturgeon, the short-snouted seahorse and the Atlantic salmon. The rocks have been listed as a Ramsar site and support a variety of small cetaceans including dolphins.
