Why was Henry Winstanley’s first Eddystone Lighthouse destroyed in 1703?

Henry Winstanley’s first Eddystone Lighthouse was destroyed in 1703 when it was swept away by a storm of exceptional severity. The wooden structure, which had been anchored to the rocks using iron stanchions, disappeared without a trace during the tempest, resulting in the death of Winstanley and those with him in the lighthouse at the time.12
