Portchester Castle dates back to the 3rd century. Despite its far-reaching history, it is one of the best-preserved Saxon shore forts in the country. The towering grey stone walls defended the Solent for hundreds of years.

The castle is managed by English Heritage from 10am - 5pm. Tickets for adults cost £8.70. The courtyard and grounds are a great place to stop for a picnic on a bike Tour.

Portchester Castle

Highlight • Viewpoint

Once the site of Portus Adurni, a Roman fort, the Porchester Castle you see today dates back to the 11th century. This vast defensive site occupies a prominent position within Portsmouth Harbour and has fantastic views southwards. The castle has seen many occupiers over the years including, briefly, the French. You can climb to the top of the keep to get the best views of the busy harbour.

These days, the castle is under the management of English Heritage and open throughout the year for visitors. To save money on ticket price, book online in advance.
