Tank ramp

Drive through Wokingham and you'll spot it quite easily - a concrete ramp sloping up from the roadside, looking rather like someone's idea of a very ambitious skate park. This is actually a World War II anti-tank obstacle, built to stop German tanks if they'd invaded. It's properly historical in the most unglamorous way possible.

There's not much to do here beyond stop, look, and contemplate what life might have felt like in 1940. You can walk around it, photograph it from various angles, and read the information board if there is one. History buffs will find it genuinely interesting - a solid piece of evidence that southern England was genuinely prepared for invasion. Kids might find it dull after five minutes unless they're mad about military engineering.

It's free and takes about ten minutes maximum, which makes it a decent waypoint rather than a destination in itself. Fair warning: there's limited parking and the site sits right on the road, so be careful if you stop to look.

If you're camping at Wellington Country Park nearby - the better of the two local parks, with a lake and proper facilities - the tank ramp is worth a quick detour on the way into or out of Wokingham town centre. It's the sort of thing that adds texture to a holiday without eating up much time. Not spectacular, but genuinely odd in the best way.
