Excavation at Happisburgh
The archaeological excavations at Happisburgh are located on the foreshore, sandwiched between the North Sea on one side and a towering cliff on the other. The deposits extend under the cliff, but the sea has destroyed the archaeological sediments on the seaward side of Happisburgh's wooden sea defences.
Most of the artefacts were found in situ during excavation, with additional pieces retrieved through sieving of all the excavated sediments. The majority were found in a series of gravel layers at the northern edge of the ancient river channel known as Happisbrgh Site 3. From just below beach level in the northernmost trench, the gravels deepen in the southernmost trench to about two metres below beach level. Earlier deposits underlying the gravel layers were recorded and sampled. A further two metres of channel sediment has been identified beneath, but it is too deep to excavate.
