But its success was threatened

[pumpui momo]

But its success was threatened by its geography. Dunwich was established on the estuary and mouth of the Dunwich River, which allowed trade to flourish. The northern part of the town was built on low-lying ground close to the river, while the centre was built on the higher ground to the south, where the soil was made of highly erodible sands and gravels. Severe storms in the 1280s and 1320s destroyed buildings and blocked the harbour on which trade depended. The lower lying areas were inundated during storms and storm surges, while the higher ground was eroded as the cliffs collapsed.
