Neilson's Monument

This is a photo of Neilson's Monument aka 'Hot Blast' aka 'the black pyramid' on the summit of Barstobrick Hill. It was erected in 1888 to commemorate James Beaumont Neilson's invention of the 'hot blast' form of iron-smelting.

On the far side of the monument are the remains of a defensive stone wall built as part of a hillfort.
