Business events in Southsea

Part of the city, with its own seafront

Southsea is not a separate town in any official sense. It is part of Portsmouth, run by Portsmouth City Council, and the ONS does not give it a population of its own: it falls inside the Portsmouth built-up area, which counted 223,305 people at the 2021 Census. What it does have is its own seafront.

The landmark there is Southsea Castle. Portsmouth's museum service, which runs it as part of Portsmouth City Council, calls it Henry VIII's own fortification, and it is a scheduled monument on Historic England's list. Its lighthouse and the lamp columns on the esplanade east of the castle are listed separately, at Grade II.

On Clarence Esplanade is the D-Day Story, Portsmouth City Council's museum of the Normandy landings, told through the accounts of people who were there; Landing Craft Tank 7074 is part of the visit.

Business in a city setting

Because Southsea is part of a unitary city, business figures are the city's. The ONS business register counted 6,095 enterprises in Portsmouth in 2026; that covers the whole city, not Southsea alone, so read it as the size of the market a Southsea business sits in rather than a count of Southsea's own firms.

Getting here

No station is called Southsea alone. Portsmouth and Southsea station is on Commercial Road, and Fratton is on Selbourne Terrace with 66 car park spaces; South Western Railway manages both. For the island, Hovertravel runs from Southsea to Ryde on the Isle of Wight, a crossing it gives as under 10 minutes.

Events listed under Southsea have met at The Hog House on Marmion Road. The rest of the city is on Portsmouth's page, and nearby towns with pages here include Gosport, Drayton and Havant. The whole stretch of coast is under Portsmouth and the south coast.
