Collyweston Slate Mine

Collyweston Slate Mine is a 0.9 hectare geological Site of Special Scientific Interest Northamptonshire. It is a Geological Conservation Review site.

This slate mine was operated until 1963, quarrying Collyweston slate, which dates to the Jurassic. The shaft exposes a section described by Natural England as "stratigraphically important", and it is the type locality for the slate.

The site is private land with no public access.
