Mill House, Monzie

The ruins at Mill House sit quietly on the outskirts of Crieff, easy to miss if you're not looking properly. What you're actually walking through are the remains of a medieval mill complex - earthworks and stone foundations that tell the story of how this corner of Perthshire once functioned. It's the sort of place that rewards a bit of poking about, especially if you've got an interest in how rural communities organised themselves centuries ago.

The site itself is free to visit and takes maybe twenty to thirty minutes to explore properly, though you could spend longer if you're taking photos or sketching plans. There's no visitor centre or interpretation boards, so you'll need to do a bit of homework beforehand or bring someone who knows their medieval mills. That said, the lack of polish is part of its charm - you're not walking through a recreated theme park version of history.

Families with younger kids might find it a bit underwhelming on its own. Older children interested in archaeology or medieval life will get more from it. Walkers doing circuits around Crieff could easily slot it into a route. The nearest caravan base is Braidhaugh Holiday Lodge about three miles away, or Comrie Croft if you want somewhere with a stronger reputation and more amenities. Either makes a decent launch point for exploring the quieter archaeological corners of Perthshire rather than just hitting the main tourist draws.
