29 Tower Street

Walking down Tower Street in King's Lynn, you'll spot number 29 - a proper slice of medieval Norfolk that somehow survived the centuries when so much else didn't. This is the real deal: a 15th-century merchant's house with the kind of timber frame and jettied upper storey that makes you understand why people got excited about architecture in the first place.

The building itself tells the story of a town that was once seriously wealthy on the back of wool and grain trading. Stand outside and you can practically see the merchants haggling, the goods being loaded onto boats heading down the Great Ouse. Inside (assuming you can access it - opening hours aren't guaranteed), the structure is what speaks loudest. Original timbers, that distinctive medieval layout, the kind of cramped spaces that make you grateful for modern ceiling heights.

This one's for history types rather than kids looking for activities. You won't spend hours here - it's more of a 20-minute stop while you're exploring King's Lynn's other medieval streets. The town centre clusters loads of these old buildings together, so pair it with a wander down the narrower lanes and a look at St Margaret's Church nearby.

If you're based at Kings Lynn Caravan & Camping Park, just 2.7 miles away, it's basically on your doorstep. Even Sandringham Camping and Caravanning Club Site at 6 miles puts it within easy reach. Admission details aren't widely advertised, so ring ahead before you plan a specific visit - typical for these smaller historic sites.
