Factor: Solway Firth

Explorer Tom Burrow Head has a non-military concrete block that looks like it fell out of a building. It’s just sitting there, minding its own business while you make up stories about it. If you can’t get in, look from the road like you’re a very polite stalker who knows exactly where to stand.

Explorer Tom Carghidown Castle in Dumfries and Galloway is a promontory fort where map makers got it wrong. They probably mistook a rock for a fortress. It’s an unassigned settlement that just wants to be left alone. Go at sunset and thank me later.

Explorer Tom Cutreoch in Dumfries and Galloway is a possible medieval castle that the seagulls think is their personal balcony. They spend all day judging anyone who walks past. It’s got that 'maybe it was something' energy going on. Bring a flask of something warm and a story to swap.

Explorer Tom Kidsdale Airfield is sitting out there judging every modern building that dares to grow up near its runways. It’s a twenty-century relic that still thinks it owns the sky, even though the planes are long gone now. The whole thing feels like a giant concrete slab waiting for a second chance at glory. Make a wish while you’re there, it’s had centuries of practice listening.
