Arminghall

In 1929 a prehistoric timber circle and henge monument site was discovered 1+1⁄2 miles north-west of Arminghall village by Gilbert Insall who had been taking aerial photographs of the area in search of new archaeological sites [1]. Whilst flying at around 2,000 feet he noticed cropmarks of a circular enclosure made of two concentric rings with a horseshoe of eight pit-like markings within it [1]. The entire site was around 75 metres in diameter [1]. The site was visited a week later by O.G.S. Crawford, who pronounced it to be the Norwich Woodhenge but it was not until 1935 that it was first excavated, by Grahame Clark [1]. His work established that two circular rings were ditches, the outer one 1.5 metres deep and the inner one 2.3 metres deep, with indications of a bank that once stood between them [1]. The pits in the middle were postholes for timbers that would have been almost 1 m in diameter [1].
