The fortifications of Portsmouth are extensive due to its strategic position on the English Channel and role as home to the Royal Navy. For this reason, Portsmouth was, by the 19th century, one of the most fortified cities in the world. The fortifications have evolved over the centuries in response to changes in tactics and technology and the area defended has increased. While the first defences focused on Portsmouth harbour, in step with the fortifications of Gosport, later defensive structures protected the whole of Portsea Island and an increasing distance inland. At the same time, the fortifications of Portsmouth and Gosport became part of the wider fortifications of the Solent. Old Portsmouth, on the southwest corner of Portsea Island, has been walled for much of its history.
Portsea Island is a flat, low-lying island measuring 24 square kilometres (9 sq mi) in area, just off the southern coast of England. The island is located within the traditional and ceremonial county of Hampshire and contains the vast majority of the city of Portsmouth.
Portsmouth Harbour is a large natural harbour in Hampshire, England. Geographically it is a ria: formerly it was the valley of a stream flowing from Portsdown into the Solent. The city of Portsmouth lies to the east on Portsea Island, and Gosport to the west on the mainland. At its north end is Portchester Castle, of Roman origin and the first fortress built to protect the harbour.
Milton is primarily a residential area of the English city of Portsmouth, Hampshire, England, on the south eastern side of Portsea Island. Milton is bordered on the eastern coast of Portsea Island by Langstone Harbour, with Eastney to the south-east, Southsea to the south-west, Baffins to the north and Fratton to the north-west.
St Agatha’s Church is a parish church in the Landport district of Portsmouth. It is affiliated to the Roman Catholic Church through the Personal Ordinariate of Our Lady of Walsingham. It is situated on the Marketway next to the Cascades Shopping Centre. It was built in 1838 and is a Grade II* listed building.
The history of Moorish Gibraltar began with the landing of the Muslims in Hispania and the fall of the Visigothic Kingdom of Toledo in 711 and ended with the fall of Gibraltar to Christian hands 751 years later, in 1462, with an interregnum during the early 14th century.
Hesse's Demi Bastion is a demi-bastion in the British Overseas Territory of Gibraltar. It is part of the Northern Defences of Gibraltar. The bastion forms a link in a chain of fortifications which ascend the lower north-west slopes of the Rock of Gibraltar, below the King's Lines Battery and Bombproof Battery. The Moorish Castle's Tower of Homage is at the top of the same incline.
Couvreport Battery is an artillery battery in the British Overseas Territory of Gibraltar.
Devil's Tongue Battery was an artillery battery in the British Overseas Territory of Gibraltar. The battery could overlook the harbour but the remains are now surrounded by reclaimed land.
Castle Batteries are a series of artillery batteries that are part of the Northern Defences of the British Overseas Territory of Gibraltar. The batteries descend from the Moorish Castle to end at the sixth and seven batteries which are known as Crutchett's Batteries. There are brick vaulted bombproof rooms (casemates) under Crutchets Battery.
The fortifications of Gibraltar have made the Rock of Gibraltar and its environs "probably the most fought over and most densely fortified place in Europe, and probably, therefore, in the world", as Field Marshal Sir John Chapple has put it. The Gibraltar peninsula, located at the far southern end of Iberia, has great strategic importance as a result of its position by the Strait of Gibraltar where the Mediterranean Sea meets the Atlantic Ocean. It has repeatedly been contested between European and North African powers and has endured fourteen sieges since it was first settled in the 11th century. The peninsula's occupants – Moors, Spanish, and British – have built successive layers of fortifications and defences including walls, bastions, casemates, gun batteries, magazines, tunnels and galleries. At their peak in 1865, the fortifications housed around 681 guns mounted in 110 batteries and positions, guarding all land and sea approaches to Gibraltar. The fortifications continued to be in military use until as late as the 1970s and by the time tunnelling ceased in the late 1960s, over 34 miles (55 km) of galleries had been dug in an area of only 2.6 square miles (6.7 km2).
The Inundation was a flooded and fortified area of ground on the sandy isthmus between Spain and Gibraltar, created by the British in the 18th century to restrict access to the territory as part of the fortifications of Gibraltar. It was originally a marshy area known as the Morass at the far south-western end of the isthmus, occupying the area adjacent to the north-western flank of the Rock of Gibraltar. The Morass was dug out and expanded to create an artificial lake which was further obstructed by iron and wooden obstacles in the water. Two small fortifications on either side controlled access to Gibraltar. The only road to and from the town ran along a narrow causeway between the Inundation and the sea which was enfiladed by batteries mounted on the lower slopes of the Rock. The Inundation existed for about 200 years before it was infilled and built over after the Second World War.
The King's Lines are a walled rock-cut trench on the lower slopes of the north-west face of the Rock of Gibraltar. Forming part of the Northern Defences of the fortifications of Gibraltar, they were originally created some time during the periods when Gibraltar was under the control of the Moors or Spanish. They are depicted in a 1627 map by Don Luis Bravo de Acuña, which shows their parapet following a tenaille trace. The lines seem to have been altered subsequently, as maps from the start of the 18th century show a more erratic course leading from the Landport, Gibraltar's main land entrance, to the Round Tower, a fortification at their western end. A 1704 map by Johannes Kip calls the Lines the "Communication Line of the Round Tower".
The Queen's Lines are a set of fortified lines, part of the fortifications of Gibraltar, situated on the lower slopes of the north-west face of the Rock of Gibraltar. They occupy a natural ledge which overlooks the landward entrance to Gibraltar and were an extension to the north-east of the King's Lines. They run from a natural fault called the Orillon to a cliff above the modern Laguna Estate, which stands on the site of the Inundation, an artificial lake created to obstruct landward access to Gibraltar. The Prince's Lines run immediately behind and above them on a higher ledge. All three of the Lines were constructed to enfilade attackers approaching Gibraltar's Landport Front from the landward direction.
The Prince's Lines are part of the fortifications of Gibraltar, situated on the lower slopes of the north-west face of the Rock of Gibraltar. They are located at a height of about 70 feet (21 m) on a natural ledge above the Queen's Lines, overlooking the landward entrance to Gibraltar, and run from a natural fault called the Orillon to a cliff at the southern end of the isthmus linking Gibraltar with Spain. The lines face out across the modern Laguna Estate, which stands on the site of the Inundation, an artificial lake created to obstruct landward access to Gibraltar. They were constructed to enfilade attackers approaching Gibraltar's Landport Front from the landward direction.
Charter Academy is a coeducational Church of England secondary school and sixth form. The school is located in the Landport area of Portsmouth in the English county of Hampshire.
