Prince Edward, the Commander in Chief of the British military, was obsessed with punctuality. As a parting gift to the people of Halifax, he gave them the Old Town Clock in 1800. The timepiece was built in 1801 in London England by the royal clock makers at the House of Vulliamy. The clock is a three tier octagonal shaped tower sitting on a Palladium-style building. Inside, three weights on drums suspended by cables power the clock. The landmark was installed on Brunswick Street in 1803, sitting high atop a hill overlooking Halifax Harbour (http://www.pc.gc.ca/eng/lhn-nhs/ns/halifax/natcul/natcul2.aspx).

Note: Perhaps Prince Edward's biggest claim to fame is he is the father of Queen Victoria.
