Lime kiln

Industrial archaeology buffs will find this well-preserved lime kiln a proper treat, though it's fair to say it won't keep the kids entertained for long. The stone structure sits quietly in the Anglesey countryside near Brynteg, a reminder of when limestone was burned here to produce quicklime for agriculture and construction.

What you're looking at is essentially a large stone furnace - not much to photograph, but fascinating if you're into how our ancestors made their living from the land. The kiln would have been fed from the top with alternating layers of limestone and fuel, with the finished lime drawn out from the bottom. Simple but effective technology that kept rural communities going for centuries.

History enthusiasts will appreciate the craftsmanship in the stonework and the insight into 19th-century industry. It's a five-minute stop at most, perfect for stretching legs during a drive around the island. The surrounding area is lovely for a short walk if you fancy exploring further.

With so many holiday parks clustered around Brynteg - from Pen Parc to Bodafon - this makes an easy detour during a touring holiday. Pop by if you're already in the area, but don't expect it to be the highlight of your trip. Worth combining with other Anglesey attractions for a proper day out.
