Nice piece of rural industrial archaeology here- the watercress beds at Letcombe Bassett. Fallen out of use now, but the concrete blocks forming the beds and leats are still visible on the Letcombe Brook in this location. Watercress (Nasturtium officinale) is a native herb and grows in on cold, running water. In the 19th century there was quite a trade in it, with many growers in the south of England sending it up to Covent Garden where it was sold.
