The Crown & Thistle PH (public house) is shown on the 1865 OS map about 1/2 mile West of Rudchester, but it's not on any other available maps.

Ironsign is recorded as the site of a former Inn on the Military Road by the Heddon-on-the-Wall Local History Society website, but I have not been able to find out any more about its history.
The buildings have evolved over the years with additions (shaded green) and demolitions (shown in red):
