ZSU-23-4 Shilka Anti-aircraft

Four massive gun barrels point skyward from this Cold War relic, a Soviet-made anti-aircraft vehicle that somehow ended up in the Norfolk countryside near Holt. The ZSU-23-4 Shilka sits like a metallic dinosaur, its tracked chassis and distinctive quad-cannon turret a stark reminder of when Europe lived under the shadow of nuclear threat.

Military history buffs will absolutely love this. The vehicle's radar-guided system was designed to shred low-flying NATO aircraft, and standing next to it gives you a proper sense of its intimidating scale. Kids fascinated by tanks and weaponry will be equally impressed, though younger ones might find it a bit scary.

What's brilliant is how unexpected it is - you're driving through gentle Norfolk farmland and suddenly there's this piece of Soviet military hardware. The contrast couldn't be more striking. Details about opening times and access seem sketchy, so it's worth checking ahead if you're making a special trip.

For families staying at Kelling Heath Holiday Park or any of the other nearby sites around the north Norfolk coast, it makes an interesting detour on the way to or from the seaside. Combine it with a trip into historic Holt for antique shops and cafes. Allow about 30 minutes unless you're a proper military enthusiast - then you could easily spend an hour examining every rivet and discussing its specifications with fellow Cold War obsessives.
