Saint Felix

You'll find the remains of Saint Felix's church just east of Sandringham, though 'remains' is the operative word here. What stands now is essentially medieval foundations and fragments scattered across a quiet Norfolk field - the sort of place you stumble upon rather than plan a day around.

The site itself tells a proper piece of local history. Felix was an Irish saint who pitched up in East Anglia back in the 630s and did the whole missionary thing, eventually getting killed for his trouble. The church that grew up here was significant enough in medieval times, but time and weather have done their work. You're looking at archaeological interest rather than a intact building - good for history buffs and anyone keen on Norfolk's Saxon roots, but families with young kids will lose interest after twenty minutes.

There's no visitor centre, no facilities, and you'll need to do a bit of detective work to find it. That said, it's free and you can visit whenever - the beauty of a site that's essentially been excavated and left to the elements. Allow half an hour if you're genuinely interested, less if you're just passing through.

It works as a side trip if you're based at Sandringham Camping and Caravanning Club Site or Pinecones just down the road. Pair it with a walk around the local lanes - there's decent countryside - but don't expect dramatic ruins or much in the way of interpretation. This is archaeology for people who actually care about the topic.
