New Minot's Ledge lighthouseIn 1860, the last stone was laid for the new Minot's Ledge lighthouse, five years minus one day after workmen first landed at the ledge. The final cost of about $300,000 made it one of the most expensive lighthouses in U.S. history. It replaced the first iron-pile lighthouse in the U.S. at the same site, built 1847-50, lighted 1 Jan 1850 but destroyed in a storm in Apr 1851. It stood off Boston's south shore, just outside Boston Harbour to warn ships of rocks that had claimed many vessels. The first granite block was laid for the new lighthouse on 9 Jul 1857. The lantern room and second order Fresnel lens were put into place and illuminated on 22 Aug 1860. This structure has withstood all storms since, and stands to this day. |
