Park Street Gate

The stone archway still stands on the edge of Brighton, a proper chunk of history that most visitors hurry past without a second glance. Park Street Gate is what's left of the old fortifications that once ringed the town - built centuries ago when defending the coast actually mattered. It's not flashy. No reconstructions, no interpretation boards cluttering the view, just weathered flint and brick doing what it's done since medieval times.

You can walk right up to it, trace your fingers along the stonework if you're that way inclined, and get a feel for how the town was physically cut off from the countryside beyond. History types will appreciate the detail - the craftsmanship is evident if you know what to look for. Kids, if they're into exploring old ruins, will find it interesting for twenty minutes or so, though there's not much to actually do there except look.

The gate sits close enough to Brighton that it's easily combined with a campsite base - Pegs and Pitches and the Brighton Caravan and Motorhome Club Campsite are both within walking distance if you fancy it, or a quick drive. Chalky Downs, a couple of miles further out, gives you more space if you prefer. Free to visit, no gates or fees, which is how heritage should work. Best in late afternoon when the light catches the old stone properly and the crowds thin out. Worth a detour if you're camping locally and fancy understanding how Brighton actually developed beyond the seafront attractions.
