I am quite fascinated by the traditional flint houses that grace Norfolk on the east coast of England. To me, "flint" means a sharp stone, but these buildings show mainly the rounded ends, combined with the brick that you see so much of in England.
These houses were quite severe in grey and white.
All kinds of buildings were made this way, and even modern buildings continue to use the flint.
This house by the coast had a decorative flint and brick wall. You can see that even the walls around houses are often made from flint.
This house was different - the flat end of the stone was used instead of the rounded end, and surrounded by small stones.
