Invermay

The earthworks at Invermay sit just outside Perth, and they're properly easy to miss if you're not looking. What you're standing at is a Roman fort - or what's left of it - from around 80 AD when the legions were pushing into Scotland. The actual remains are subtle: grassy banks and ditches that don't immediately scream "ancient military installation" unless you know what you're looking at. That's either the appeal or the letdown, depending on your tolerance for archaeology that requires some imagination.

It's a decent spot if you're into Roman Britain and have already done Hadrian's Wall elsewhere. The site itself won't take more than twenty minutes to walk around, so it works best as part of a bigger day out rather than a destination in itself. History buffs and students of Roman occupation will find it worthwhile. Families with restless kids might find it a bit underwhelming - there's no visitor centre, no interpretation boards worth mentioning, and the view is just fields.

The nearest caravan parks - Perth Caravan Park is five miles away, Maycroft Retreat closer at three miles - make it an easy add-on if you're based in the area. Perth itself has proper attractions if Invermay doesn't grab you. Head there first, get a sense of the town, then decide if a quick detour to the fort fills the afternoon or feels like a sidetrack. It's free to visit and accessible year-round. Not a must-do, but solid for the Roman history crowd.
