The Aubreys

You'll find yourself standing in a field east of Hemel Hempstead looking at what remains of a Neolithic causewayed enclosure - basically a series of ditches and banks that someone dug out roughly 5,500 years ago. The Aubreys isn't dramatic. There are no standing stones, no reconstructed huts, no visitor centre with coffee. What you get is the earthworks themselves, subtle bumps and hollows in the landscape that take a bit of imagination to read as ancient architecture.

This is proper archaeology territory - the sort of place that makes sense if you've read up a bit beforehand or you're genuinely interested in how Neolithic communities organized their settlements. The causewayed enclosure was likely a meeting place, a gathering ground for scattered communities rather than a permanent settlement. Standing there, you're looking at evidence of early ceremonial or trading activity in Bronze Age Britain.

Walkers and history enthusiasts will find it worthwhile, especially if you're combining it with a proper tramp through the Chilterns. The site itself won't take long - half an hour maximum - but it rewards a slow look. Families with younger kids might struggle; there's not much here to hold their attention unless they're already keen on archaeology.

It's free and accessible, though there's no formal infrastructure. Check conditions before visiting - wet weather turns fields muddy. If you're based at Fuzzy's Farm or Merlin Farm nearby, it's an easy detour rather than a destination in itself. Worth the drive if you're into this period, but don't expect Stonehenge.
