The train from London Waterloo puts you into Portsmouth and Southsea station at a quarter past five. The station is functional rather than decorative — a useful starting point, not a destination — and you are out through the barriers and onto the street before the platform has emptied. It is October, the light is already going, and the air carries salt from somewhere south.
Old Portsmouth is roughly a mile on foot, if you take it directly. The streets tighten as you get further from the commercial centre, the terraces running closer together, the horizon ahead widening as the ground stays flat and low. Portsea Island sits six metres above sea level across its whole length, and you feel that flatness as you walk — nothing rises, nothing blocks the sky.
The Royal Garrison Church appears before you expect it. It is not set back from the street. It stands at the edge of Grand Parade, close to the harbour mouth, and the first thing you notice is the sky where the roof should be. The nave is open — has been open since May 1941, when a bombing raid took the roof and did not put it back. English Heritage manages the site now, and the roofless nave is maintained as it is: grass floored, open to October cloud, with the medieval chancel still covered and intact at the east end. The church was founded in 1212 as the Domus Dei, a hospital and chapel for the port. Catherine of Braganza married Charles II here in 1662. Then the war. Then the sky.
You stand outside for a moment. There is something in the combination — the Norman stonework, the open nave, the darkness coming in from above — that does not require interpretation. It simply sits there, being what it is.
Portsmouth Cathedral is a short walk away, along the edge of the old town. Its foundation stone was laid in 1185, which makes it older than the church you have just left, though it does not feel older — the twentieth-century nave extension gives it a more complicated interior, medieval and modern in the same building. It is free to enter outside services, and at this hour it is quiet. The tower and lantern above the crossing catch what is left of the evening light.
By the time you reach the harbour mouth itself, the lights of Gosport are visible across the water. That is where HMS Alliance sits — a 1945 submarine at the Royal Navy Submarine Museum, boardable, preserved, on the other side of a short ferry crossing from Portsmouth Harbour Pier. You did not cross today. That is a morning job, better done in daylight when you can see the harbour properly from the water.
The Spinnaker Tower is lit behind you, rising above Gunwharf Quays. It opened in 2005 after a long and publicly debated design process, and celebrated its twentieth year in 2025. From the harbour mouth it reads clearly as the new city marking its place alongside the old one — a sail shape above a redeveloped docklands, visible from most of Portsea Island on a clear night.
You walk back along the waterfront toward the station. The Historic Dockyard gates are closed at this hour, HMS Victory and HMS Warrior dark behind them. That is tomorrow — a full morning, probably most of a day if you go through properly. The dockyard holds enough naval history for several visits: the Victory, the Warrior, the Mary Rose raised from the Solent in 1982 after four centuries on the seabed.
For now: the harbour mouth, the roofless church, the lights across the water. October in Portsmouth earns its keep.
