Mereworth Castle

The first time you spot Mereworth Castle from the lane approaching it, you'll understand why it's caused such a stir in Kent for nearly three centuries. This isn't your typical crumbling fortress - it's an 18th-century country pile built in the Palladian style, all geometric perfection and classical proportions, sitting rather grandly in its own grounds near Maidstone. The main house itself isn't open to the public on any regular basis, but the grounds and the distinctive tower - a proper eye-catching structure - are visible from the perimeter, and there's genuine appeal in just walking around the estate to take it in from different angles.

Architecture enthusiasts and history types will find plenty to appreciate here. The castle was designed to be a statement of wealth and taste, and you can read that intention in every symmetrical line. It's not a day-long activity by any means - reckon on an hour's wander if you're thorough - but it breaks up a walk nicely if you're exploring the area around Maidstone.

The real value here comes when you're basing yourself at one of the nearby parks. River View Camping sits just 2.2 miles away, making this an easy evening detour after settling the tent or caravan. The Hop Farm, 3.6 miles out, is another solid option if you're after something slightly more developed. Neither will give you castle interiors or formal tours, but for a bit of architectural interest and a gentle walk through Kent's countryside, it's worth the detour. Best visited on a clear day when the light catches those pale stone walls properly.
