Portsmouth Harbour

Pewit Island is a small island located in the north western section of Portsmouth Harbour. Historically it appears to have been connected to the mainland via a manmade shingle causeway, parts of which still exist. The island has been colonised by oak and blackthorn scrub and is home to species including sea lavender and golden samphire plants. The island is currently a Hampshire and Isle of Wight Wildlife Trust nature reserve.In 1857 plans drawn up to improve the defences of Portsmouth included building a fortification on the island. The plans were later modified in the face of improved artillery technology and the fortification was never built.

Portchester Castle is a medieval fortress that was developed within the walls of the Roman Saxon Shore fort of Portus Adurni at Portchester, to the east of Fareham in Hampshire. The keep was probably built in the late 11th century as a baronial castle and Portchester was taken under royal control in 1154. The monarchy controlled the castle for several centuries and it was a favoured hunting lodge of King John. It was besieged and captured by the French in 1216 before permanently returning to English control shortly thereafter. Occupying a commanding position at the head of Portsmouth Harbour, in the medieval period Portchester was an important port. The castle saw the embarkation for several campaigns to France led by England's kings. In anticipation of a French invasion during the first quarter of the 14th century, Edward II spent £1,100 repairing and reinforcing Portchester Castle. A plot to overthrow Henry V was discovered and the culprits apprehended at Portchester; this event features in Shakespeare's play, Henry V. Later in its history, the castle was used as a prison. Today Portchester Castle is a Scheduled Ancient Monument, and a Grade I listed building. The castle has been in the ownership of the Southwick Estate since the 17th century but is managed by English Heritage and open to visitors throughout the year. The Norman church, St. Mary's, which stands in the south-east corner of the grounds, falls within the Anglican Diocese of Portsmouth.

Burrow Island (also known as 'Rat Island' or 'Ratty') is a tidal island in Gosport, United Kingdom. The island overlooks Portsmouth harbour. At low tide a spit connects it with Priddy's Hard. It has been suggested that the name dates from the 17th century and is derived from being within the borough of Gosport.Between 1678 and 1679, a fortification named Fort James was constructed on the island under the direction of Bernard de Gomme. It took the form of a square tower 19 ft tall. The fortification was apparently allowed to decay with George Byng commenting on its poor condition in a letter written in either 1707 or 1708. It appears that a rebuilding to a new design was proposed on 1750 but this never took place. What were by then the ruins of the fort were partially demolished in 1827 and nothing now remains above ground level. It has been claimed that King Stephen built a fortification on the island but this is unlikely to have been the case.Burrow Island is owned by the Ministry of Defence, and public access is not permitted; despite this, at low tide some members of the public have ventured onto Burrow Island. It is a popular spot to go fishing. It is known that some have found unique coloured glass bottles that had been washed up on the island. Burrow Island was once used as a burial ground for convicts; several human skeletons were discovered on the island early in 2014. They are believed to be from the 19th century and are the remains of convicts or prisoners of war who had been buried on the island.Burrow Island is one of 43 (unbridged) tidal islands which can be walked to from the mainland of Great Britain.
