In the books
In the A Song of Ice and Fire novels, Hammerhorn is the seat of the main line of House Goodbrother. It is a large, square castle. The stones used for its construction were quarried from the cliff behind it. Below its main entrance lie the openings to the mines and caves that the thralls in service to House Goodbrother toil in.
