Langley Castle

The first thing that strikes you about Langley Castle is how genuinely medieval it feels - a proper square tower with battlements, sitting alone on a Northumberland hillside near Hexham. Built in 1365, this is one of England's oldest castles still standing, and you can actually stay here in en-suite rooms if you fancy sleeping where medieval lords once plotted. It's not a sprawling ruin; it's compact, intimate, and absolutely real.

Inside, you'll find a working hotel with a restaurant rather than a museum setup, which means the castle has kept its soul. The rooms occupy the original tower - genuine stone walls, flagged floors, the lot. There's a decent restaurant on site too, so you can dine within castle walls without pretending. History buffs will appreciate the unadulterated authenticity; families with young kids might find it a bit sparse for entertainment, though teenagers tend to find the whole staying-in-an-actual-fortress thing properly cool.

If you're basing yourself at one of the nearby glamping spots - Langley Dam Glamping is just over a mile away, or Panoramic Pods at 4.5 miles - you could visit for a meal or stay overnight without the caravan park feel. The castle sits well within the wider Northumberland park holiday circuit, close enough to Hexham for supplies and exploration.

Admission works through dining or staying; there's no casual day-visitor fee as far as I can tell. Ring ahead to confirm current arrangements. Worth the detour if you're serious about medieval castles, less essential if you're after something flashy.
