Dear Bernard, I live in County Cork, Ireland, in a road called Martello Park. I’ve gathered now that the road-name is because of the big tower above our hill called a Martello Tower, which the locals insist was built over 200 years ago by the British to guard against a French invasion (our house is overlooking Cork harbour) (there’s also a big channel nearby called Drake’s Pool, where Francis Drake once outwitted a Spanish pursuit by hiding up it, and it’s been called Drakes’s Pool ever since) but aside from Drake, do you know where the word Martello comes from? Thank you, Paul Reid.
