During the Bronze Age (about 1500 BC) tribes sometimes called the Urn people started to settle in the area. They built numerous stone circles, examples of which can be found on Ash Cabin Flat, Froggatt Edge and Hordron Edge (Hordron Edge stone circle). Two Early Bronze Age urns were found at Crookes in 1887, and three Middle Bronze Age barrows found at Lodge Moor (both suburbs of the modern city).
