Pevensey Castle began as a Roman fort around AD 290 and is the largest of the Saxon Shore forts. Its massive walls, more than 500 metres long, still stand almost to their full height. In 1066 William the Conqueror landed here to begin his invasion of England, and the Normans built a stone keep and fortress inside the Roman defences.

Tip: Book advance tickets online to save money. Battle Abbey, the 1066 battlefield, is about 9 miles away.

SEA LIFE Brighton opened in 1872 as Brighton Aquarium and is the world's oldest continually operating aquarium.

Charleston, in the village of Firle, was the country home of the artists Vanessa Bell and Duncan Grant, and for decades a meeting place for the Bloomsbury Group. The rooms on show are covered in their work, with murals, painted furniture, ceramics, textiles and paintings. The collection also includes pieces by artists such as Renoir and Picasso.

Tip: Check the Charleston website before you set off, as the site closes at times between exhibition seasons.

Battle Abbey, run by English Heritage as 1066 Battle of Hastings, Abbey and Battlefield, is the site where William the Conqueror's Normans met King Harold's English army. The abbey was founded by William soon after the conquest, said to be on the spot where Harold died.

Tip: Head to the visitor centre first to get the story of the battle, then take the audio tour round the battlefield.

Herstmonceux Castle is a brick-built castle in East Sussex, dating from 1441. It is one of the oldest significant brick buildings still standing in England, built with bricks made from local clay by builders from Flanders. Its story runs from a ruined shell, left after the interior was demolished in 1776-77, to a major restoration in the early twentieth century.

The Seven Sisters are a series of chalk sea cliffs on the English Channel coast, running between the mouth of the River Cuckmere near Seaford and the headland of Beachy Head outside Eastbourne. Each of the seven crests is separated by a dip, the remains of dry valleys in the South Downs that the sea is slowly eroding.

Bodiam Castle is a 14th-century moated castle near Robertsbridge in East Sussex. Sir Edward Dalyngrigge built it in 1385 with the permission of Richard II, ostensibly to defend the area against French invasion during the Hundred Years' War. It has no keep. Instead, the chambers were built around the outer walls and inner courts, with towers at the corners and the entrance, topped by battlements.

Tip: You don't need to book in advance, but the car park uses the JustPark app, so download it and set up an account before you arrive. The towers are reached by steep spiral staircases.
