Pillow Mounds

You'll find these low, grass-covered mounds scattered across a field near Llanidloes, and honestly, they're easy to walk past without realising what you're looking at. Pillow Mounds are medieval rabbit warrens - artificial breeding grounds where rabbits were farmed for food and fur. Walk around them properly and the landscape suddenly makes sense: each mound is a burrow system, often arranged in neat rows across the slope.

It's a genuinely interesting spot if you're into medieval life and land use, though I'll be straight with you - it's not visually dramatic. You won't get that jaw-dropping moment you'd have at a castle or standing stone. What you do get is a real sense of how people managed their resources centuries ago, and the quiet satisfaction of spotting something most tourists miss entirely.

Historically minded walkers will spend a good 45 minutes to an hour exploring the site properly, poking around to spot different mounds and trying to work out the warren layout. Kids might manage 20 minutes unless they're genuinely into archaeology. It's free and accessible, which helps.

Based near Llanidloes, it slots well into a walking holiday using one of the nearby camping spots - Elan Oaks, Glangwy Farm, or Wyeside are all within five miles and solid bases for exploring the Mid Wales moorland. Come in autumn when the light's better for spotting the mounds' shadows.
