The hidden gems near Portsmouth are Southsea Rose Garden, Southsea Castle, Eastney Beam Engine House, Spitbank Fort, Farlington Marshes, Racton Ruin, Bursledon Brickworks Museum and Old Winchester Hill.
Portsmouth rewards anyone willing to wander a little beyond the waterfront, with historic forts, wild marshes and hilltop follies all within reach. Along the Southsea seafront you will find the fragrant Rose Garden set in old fort earthworks, the Tudor guns of Southsea Castle and, a short way east, the preserved Victorian engines of the Eastney Beam Engine House.
Out in the Solent, Spitbank Fort rises from the water offshore. To the north, Farlington Marshes teems with birds on its neck of reclaimed land.
Venture further and the rewards grow: east into West Sussex stands the eerie Racton Ruin near Chichester, while west in Hampshire the Bursledon Brickworks Museum preserves a steam-driven brick factory near Swanwick. North again, Old Winchester Hill crowns the Meon valley with its Iron Age ramparts.
Some sit close to home, others a proper drive away. Here are eight hidden gems to seek out near Portsmouth.
Southsea Rose Garden

Wander the Southsea Rose Garden Laid out within the earthworks of the old Lumps Fort on the seafront at Southsea, beside Canoe Lake and around 3km from Portsmouth's centre, this public rose garden was created in 1952. Beds of hybrid tea and climbing roses grow among pergolas, and a Japanese garden was added alongside in 2000 to mark the city's twinning with Maizuru in Japan.
The surviving fort ramparts give raised views over the Solent. Boards nearby recall the Cockleshell Heroes raid of 1942, which trained on this shore.
Southsea Castle

Explore Southsea Castle This artillery fort on the Southsea seafront was built in 1544 for Henry VIII as part of his coastal defences, with a square keep, gun platforms and angled bastions ringed by a dry moat. A whitewashed lighthouse was added in 1828.
Visitors walk the ramparts, keep and moat, see old cannon and displays, and take in wide views over the Solent, from roughly the spot where Henry is said to have watched his warship the Mary Rose sink in 1545. The city council has run it as a museum since 1967, around 3km from the centre, and entry is free.
Eastney Beam Engine House

Step into the Eastney Beam Engine House This Victorian pumping station at Eastney, around 3km from Portsmouth's centre, was built in 1887 as part of the city's main sewage works. Inside stand two large rotative beam engines made by James Watt and Company, which once pumped the city's sewage and are now kept as a preserved industrial museum.
A separate gas engine house on the site holds early-20th-century engines. Run by volunteers for the city council, it is free but opens only on a few days a year, roughly the last Sunday of the month.
Spitbank Fort

Spitbank Fort Round and squat, ringed with iron armour and built of granite, this Victorian sea fort sits alone on a shoal in the Solent off Portsmouth. It belongs to a ring raised in the 1860s and 1870s against a French attack that never came, an inner line drawn up behind the larger forts further out to sea.
For a while it lived a second life as a small hotel and events venue, opened in 2012, but that closed and the fort went under the hammer at auction in 2024, so no one can visit for now. Reached only by boat, it is a sight to admire from the water rather than a place to land.
Farlington Marshes

Watch birds at Farlington Marshes On a low neck of land reclaimed from Langstone Harbour on the northern edge of Portsmouth, this coastal grazing marsh is run by the Hampshire and Isle of Wight Wildlife Trust. A sea-wall path of about two and a half miles loops around freshwater and brackish marsh and a lagoon, and it ranks among the region's best places for birds, with large winter flocks of Brent geese, waders, short-eared owls and passing migrants.
It is a protected site of international importance, around 5km from the centre, and old wartime decoy control bunkers survive on the marsh.
Racton Ruin

Seek out Racton Ruin Around 16km east of Portsmouth, this ruined eighteenth-century folly tower stands among farmland in the South Downs near Chichester in West Sussex, so it makes a longer trip that way. Triangular at its base with a round turret at each corner, it rises as a roofless, floorless brick shell, most of the flint that once faced it now gone, and it can be seen for miles.
Built between about 1766 and 1775 for the Earl of Halifax, it once stood four storeys and some eighty feet tall, though its purpose, whether summerhouse or lookout over the harbour, was never clearly recorded.
Bursledon Brickworks Museum

Discover the Bursledon Brickworks Museum The Brickworks Museum, long known as Bursledon Brickworks, is a preserved Victorian brick factory at Swanwick in Hampshire, around 17km northwest of Portsmouth and a longer outing in that direction. Built in 1897 and worked until 1974, its surviving buildings, kiln, chimney and drying sheds are listed, and they still hold the original steam engine, clay machinery and continuous kiln, said to be the last steam-driven brickworks of its kind in Britain.
Run now by volunteers, it opens seasonally with working steam days, narrow-gauge railways, a heritage bus collection and a cafe. It sits on Swanwick Lane, the Bursledon in its name being the nearest old parish.
Old Winchester Hill

Walk up Old Winchester Hill On the eastern side of the Meon valley in Hampshire, around 20km from Portsmouth, this hill rises to about 197 metres, despite its name lying some eleven miles from the city of Winchester. Its summit carries an Iron Age hillfort, with grassy banks and ditches still clear, and Bronze Age burial mounds inside and around the enclosure.
It is a national nature reserve of chalk grassland, rich in orchids and in butterflies such as the chalkhill and Adonis blue, with wide views over the valley. The South Downs Way crosses it.
