Toot Hill

Standing stones and grassy earthworks mark what's left of this medieval motte and bailey castle, perched on a modest hill just outside Alford. You'll find the remains about as understated as castle ruins get - no towering walls or dramatic gatehouses here, just the telltale bumps and ridges that hint at its 12th-century origins.

The site's proper appeal lies in its simplicity and the views across the Lincolnshire countryside. History enthusiasts will appreciate tracing the outline of the original fortifications, while dog walkers often use it as a pleasant stopping point. Kids might need a bit of imagination to get excited about what amounts to some raised ground and scattered stones.

Access appears to be free, though there's precious little in the way of facilities or interpretation boards. Twenty minutes is probably enough to explore the site thoroughly, unless you're planning a picnic on the surrounding grassland. Best visited on a clear day when you can properly appreciate the strategic position the Norman builders chose.

For those staying at nearby holiday parks like Haven Golden Sands or the camping sites around Mablethorpe, it makes a decent diversion if you're already exploring the market town of Alford. Combine it with a visit to the town's windmill and you've got a pleasant morning's outing, though it's hardly worth a special journey on its own.
