 A total of twenty forts — nearly one for each of Bermuda's square miles — would be erected by 1800, most of them to guard St. Georges.By 1783, over half of the colony's cannons ringed the eastern parish.These forts did not follow the conventional bastion-style that then prevailed in Europe; instead they most resembled the fortifications built under Henry VIII along the coast of southern England in the early 16th century.
