prize8-2, Exercise 3: A timeline from the Pharos to 1816

Model answer (check the details; items marked * are the ones to check first):

Early 3rd century BC   The Pharos of Alexandria is built *
1st or 2nd century AD  Roman towers at A Coruña, Dover and Boulogne *
14th century           The Pharos is damaged by earthquakes and falls *
1514                   Trinity House receives its royal charter *
1636                   Coal beacon established on the Isle of May *
17th century           Private patents grant rights to build lights and charge tolls *
1786                   The Northern Lighthouse Board is established *
1790                   The Tower of Hercules is restored *
1816                   Robert Stevenson's lighthouse on the Isle of May is lit *

Why check: early dates often rest on later writers, and towers have been rebuilt so that the date of the structure and the date of the first light may differ.

Care: the dates come from general knowledge. Confirm each against the authorities' histories and archaeological guides.
