Yep, Warkworth is the village with the castle.
I suspect Bamburgh castle might be one of the places you'd be visiting. Barter Books is great for a rake around in. Cragside house just outside Rothbury is interesting to look around, it was the first house in the UK to be powered by hydro-electricity. Plus you can get nicely lost in the grounds and not see a soul.

I suspect you may have already seen this, but just in case www.visitnorthumberland.com/ The only trouble with Northumberland is it's quite a large county and it can take a while to get around it.

Simonside is a great walk to do as well, the view at the top of the crag is stunning.
