Hi Wynne-12
Grindley Brook is most famous for a set of staircase locks on the Llangollen Canal which lies at a junction with the A41 trunk road.
It is a busy spot for tourists these days, with a shop & pub & lots of people walking on the towpath, on canal boats & on the long-distance walks in the area.
The village is named after James Grindley, the engineer, I think. The area would have been economically very important in the 1830s with the canal & the trunk road.
