Georgian Inventions Trail

The world’s first CAST IRON BRIDGE was built over the River Severn at Coalbrookdale in 1779 by Abraham Darby III.

This is part of the Cromford Mills ‘Inventions’ trail for families. To find out more, go to

There are 10 trail locations, stretching from the top of Church Walk by the A6, to just past the first bridge on the canal.

To collect your prize, rearrange the letters on the posters into something that was invented by Sir Richard Arkwright, and tell the mill shop!
