Old Radar Station

Concrete bunkers and rusting metal structures dot this windswept clifftop site, remnants of Cornwall's wartime coastal defences. The Old Radar Station near Looe offers a fascinating glimpse into the Second World War's technological frontline, where operators once scanned the horizon for enemy aircraft and ships.

Walking among the abandoned installations feels properly atmospheric - though you'll need to use your imagination since there's little in the way of interpretation boards. History enthusiasts will appreciate the authentic feel of exploring these untouched ruins, while families might find the kids lose interest after twenty minutes unless they're particularly keen on military history.

The coastal location means cracking views across the Channel when the weather's clear, making it well worth combining with a clifftop walk. You can easily reach it from any of the nearby holiday parks around Looe - Waterside and Tencreek Holiday Park are both less than two miles away.

Expect a bit of a trek across rough ground to reach the best-preserved structures. There's no visitor centre or facilities, so pack a flask if you're planning to linger. The site's completely free to explore, though do watch your footing around the concrete structures.
