All I can say is that there are a lot of castles in this country and I’m sure I haven’t got them all. I have tried to remember some of the differences between a tower house or pele tower and a castle when I’ve made my list. A pele tower was not designed to be lived in the whole time – it was more of a refuge when reivers and clan enemies arrived on your doorstep. Aydon Castle is actually a fortified manor house rather than a castle but it’s on the list because it’s such a lovely example. The list is in no particular order and I have missed a particular favourite of yours I can only apologise. Please add it to the comments section. I have written about rather a lot of castles over the years. If you select “castles” from categories on the right hand side of the blog you will be able to find them.
Cumberia and Westmorland:
Naworth Castle is actually a pele or peel tower depending on how you would like to spell it. https://thehistoryjar.com/2017/05/11/naworth-castle-and-the-dacres/ Highead Castle and Thistlewood Tower, both in Cumbria are also peel towers. Thistlewood was in the possession of the Dacre family as was Naworth. https://thehistoryjar.com/2017/05/16/highead-castle-and-thistlewood-tower/

Carlisle Castle – first built in 1092 by William Rufus. I don’t think I’ve ever written specifically about the castle although it has turned up in quite a few posts including about Andrew de Harcla who was besieged by the Scots.
Askerton Castle – a fortified manor house rather than a castle. Now a farm.
Dacre Castle – it’s actually a tower house rather than a castle but it looks remarkable like a castle from the exterior.
Rose Castle – the home of the Bishops of Carisle https://thehistoryjar.com/2017/05/22/rose-castle/

Castles, peel towers and fortified manors sprout like mushrooms in the NorthEast and I suspect this is one of the reasons why I love visiting the area.
Thirlwall Castle – built close to Hadrian’s Wall from dressed stones quarried from the wall. It’s also a tower house rather than a castle proper.

And that is, as they say, that! If this has wetted your appetite to visit a few castles when we’re all allowed out then I would recommend the Collins English Castles from its Little Books series. Others of you may have your Observers Book of Castles on your bookshelves. It has been very pleasant thinking of all the castles that I have visited – less pleasant trying to identify my photographs!
