When looking for windmills I happened to stumble on an article on this. It's known as little Switzerland in Norfolk. It was a massive series off marl pits, which were quarried for use in agriculture for soil. Small canals were run through the land this enabled the wherries to transport the marl to the river. The soil was heaped up creating a mountain style landscape which led to its name. It was the large bridge I wanted to see, known as the high low bridge. Built high enough for the wherries, but with a low approach to the top of the bridge. The quarry operated during the 18th and 19th century and closed in 1877. The bridge is now left with trees taking over the former pits. I was determined to find this mythical bridge, so a little research I had a rough location quite quickly. I took the trek to it and found it eventually hidden in woodland. I have a love of old brick bridges and their construction, and this one is a beauty.
