Mum and I booked to come into England once more this coming April. We did a fair bit of your touristy stuff on our last excursion over (Tower of London, Stonehenge etc) and looking to visit some much older and historic stops in the Country. Castles! The only 2 of note I know of are Warwick and Arundel but am looking for any suggestions on others? We will have rail passes to get us anywhere so that's no issue. So fire away NSC suggestions on Castles in England?
