Cleator Moor developed rapidly in the 19th Century, as the industrial revolution demanded more and more coal, limestone and high grade iron ore. Cleator Moor and all the villages around it - Frizington, Rowrah, Keekle, Bigrigg - were a maze of railways and mines which produced the materials for iron works in Cleator Moor and Workington. Early in the 20th Century supplies began to decline, and now there is little industry here. The population is about 7500.
