Portchester Castle

　　Portchester Castle is a medieval fortress and former Roman fort, situated in Hampshire in southern England, east of Fareham. It is a scheduled ancient monument and a Grade I listed historic building in the UK. Since the 17th century, the castle has been owned by the Southwick Estate and is now managed by English Heritage. It is open to the public year-round as an important historical site in Britain.

　　In the late 3rd century, the Romans built a series of defensive forts along the southern and eastern coasts of England to protect their colonies from Saxon invasions. The fort at Portchester became an excellent harbor for the concealed Roman fleet. Around the year 1090, William Mauduit, lord of the local manor, constructed a small Norman castle in the northwest corner of the fort. By around 1180, the wooden palisade had been replaced with stone walls, during which time King John frequently stayed at Portchester Castle. During the 14th century, the main structure of the castle was renovated and rebuilt, and Richard II transformed it into a luxurious palace. The castle lost its former significance after Henry VII established a royal shipyard at Portchester. In the 19th century, it also served as a prison during the Napoleonic Wars, holding over 7,000 French prisoners.

　　Today, Portchester Castle has become a recreational attraction that can be entered free of charge. The interior is often used for exhibitions and is a popular destination for school field trips. Its coastal proximity also makes it a regular spot for anglers.
