Stone walls have historically been used to designate property lines, but there are many other functional and aesthetic reasons for adding a natural stone wall to your landscape. This gallery shows many types of stone walls, from very simple and formal, to historic, to sleek and minimalistic. You'll note that a stone wall can be very low-profile to multi-terraced and "casually-placed" or meticulously pieced. Clicking any image will open a slideshow of larger images.
