Many crinkle crankle walls are found in East Anglia, England. There the marshes of The Fens were drained by Dutch engineers, starting in the mid-1600s. They apparently introduced the idea.  The county of Suffolk has at least 50 examples, twice as many as in the rest of the country. The term "crinkle crankle" is said to derive from a Suffolk dialect. The crinkle crankle wall running from the former manor house to All Saints' Church in the estate village of Easton is believed to be the longest existing example.
