You can build with chalk, but it’s a soft rock and not an ideal building material, but along with the chalk goes flint, which is found in the upper layers of the chalk and is used in many places for building. Flint, on the face of it, isn’t an ideal building material either. It occurs in rounded nodules, and to build a wall out of these small lumps of flint, you usually need a lot of mortar. When napped or split into workable pieces with a flat side to form the face of the wall it often looks black or grey, and this can be overwhelming in large stretches. So for visual reasons and for structural ones (lots of mortar can make a weak wall) the builders of the chalk areas have devised lots of ways of combining flint with other materials – bands or strips or blocks of other more w...
