The ruins of a historic castle sit on the edge of a sea cliff in the Castle Sinclair Girnigoe Caithness wall mural. The deep blue water of the sea behind the castle meets with a bank of white clouds at the horizon line, showing the beautiful natural view that was once enjoyed from the castle's now ruined towers and ramparts. Photographed by travel photographer David Wall, the stones of this popular tourist attraction are now overrun with grass and moss, leading to a sublime and ancient atmosphere. Use this historic landmark mural to add a historical note to your interior design or create an interesting focal point in a business.
