What is "salterbeck"

Salterbeck is a council housing estate on the south side of Workington which was built during the 1930s on farmland for steelworkers and their families relocating to the area. Roughly 70% of the houses are now owned by Impact Housing Association and roughly 30% are privately owned. Salterbeck is bordered by Westfield and Mossbay to the north and Harrington to the south.
