Architectural Drawings of Minot Ledge Light House 1855. Work started on the current lighthouse in 1855, and it was completed and first lit on November 15, 1860, with a final cost of $300,000 that made it the most expensive light house that was ever constructed in the United States. The lighthouse is built of large and heavy dovetailed granite blocks, which were cut and dressed ashore in Quincy and taken to the ledge by ship. The lighthouse was equipped with a third-order Fresnel lens.
