23 High Street

Walk down King's Lynn's High Street and you'll spot a building that's clearly seen a few centuries go by. Number 23 is one of those addresses that rewards a proper look - the kind of place where the fabric of the building itself tells you something about Norfolk's mercantile past.

It's a historic site, which means the bones of the place matter more than the contents. If you're into Georgian or medieval architecture, the bones are worth studying. The street frontage carries the weight of history in its timber framing and the way it sits among its neighbours. You're looking at how ordinary townspeople once lived and worked, not some grand manor.

History buffs will spend twenty minutes here happily enough, taking in the details. Kids might find it less gripping - unless yours are architecture enthusiasts already. It's the kind of stop you'd make if you're working your way through King's Lynn on foot, not a destination in itself.

The useful bit: it's free to look at from the street, and you lose nothing by visiting. Opening hours aren't relevant since it's essentially an external viewing experience. If you're based at Kings Lynn Caravan & Camping Park (less than three miles away) or the Sandringham site further out, adding a wander through the town centre takes no effort. Pair it with King's Lynn's other period buildings and the riverside walk, and you've got a solid morning's activity. Worth the detour if you're already in town, not worth driving specifically for.
