The abbey steadily became prosperous, acquiring lands in north
Cumberland and undertaking reclamation work along the Solway. In 1301 it was granted a market at
Skinburness, together with permission to build a church. Following violent storms which devastated Skinburness, both permissions were transferred to
Newton Arlosh, where the abbey built a heavily fortified
chapel of ease. Experience had shown that the abbey's Scots origins did not protect it from attacks by Scots raiders, from whom it suffered repeatedly from 1216 onwards, with a particularly severe attack in 1319, by
Robert the Bruce, despite his father being buried there. The community established a daughter house at
Grey Abbey in
County Down in
Northern Ireland in 1193. ==Dissolution==
