Maiden Castle from afar? It’s basically Dorset’s ultimate, oversized plate of grass lasagna. A massive, lumpy green ripple on the horizon that makes you think, "Wow, the Celts really hated mowing the lawn."

Hardy’s Monument: climb 120 steps to look like a sweaty mess, just so you can stare at Dorset, the sea, and sheep that look like popcorn. On a clear day, you can see your house!

Quite casually, you'll find yourself standing in the middle of a millennia-old place, which Celts, Romans, Anglo-Saxons, and Normans have repeatedly reshaped to suit their culture and needs. Those familiar with Old Sarum will recognize or compare many things (Salisbury). Two information panels allow you to immerse yourself in this tranquil place.
