1600s

1670's The Lowestoft Lights were re-built again. A few years previously John Clayton had erected a coal-light a couple of miles north at Corton. Clayton's efforts to build lighthouses at various locations around the coast were seen by Trinity Brethren as being a threat to their monopoly.

Two elderly Lowestoft women, Rose Cullender and Amy Denny, were tried for witchcraft at Bury St Edmunds Assizes, having been accused by their neighbours. Found guilty, they were sentenced to death by judge Sir Matthew Hale and hanged at Bury St. Edmunds on March 17th.

Lowestoft was badly damaged in a substantial fire in 1645. Beginning in a fish house at the base of Lighthouse Score, buildings as far south as Rant Score and to the west of High Street around Crown Street were damaged or destroyed.
