Iron, 28.20 grams, 92.47 mm. Circa 13th century AD. A substantial medieval key comprising a thick (about 3mm) bow attached to an elliptical shaft. The bit is a rectangle with a toothed fore edge and remains of an additional toothed element below. The junction of the shaft and bow is strengthened with a ribbed collar. The key is very robust and must have been used with a large lock, probably for the door of a prominent building.
