Rose Castle near Dalston in the north of the county is about to be converted into an international Christian centre for reconciliation.
The cost of the work to change the use of this Grade I listed building is estimated at £5million.
The castle was home to the bishops of Carlisle from 1230 to 2009.
In 2011, the Church Commissioners decided that it was no longer fit for purpose and should be sold.
The history connected to Rose Castle is fascinating, as originally it was twice the size and housed a private army as well as the bishop and his retinue.
Many battles have been fought with the Scots in and around the area of the centuries.
At last a plan is in place to save this wonderful castle from being sold into private ownership and will be put to good use helping in conflict resolution and to aid greater understanding between the different faiths.
