You stand along the stone parapet of Dry Dock 1, universally hailed by civil engineers as one of the greatest maritime engineering achievements in American history. Authorized by Congress in 1827 and completed in 1833 to designs by brilliant civil engineer Loammi Baldwin Jr., this massive granite dry dock was one of the very first two naval dry docks constructed in the United States, alongside its twin at Norfolk, Virginia.
Measuring three hundred and forty-one feet long and thirty feet deep, Dry Dock 1 was constructed entirely of massive blocks of hand-chiseled Quincy granite, fitted together with such astonishing precision that the stone seams remain watertight nearly two centuries after construction without the use of modern caulking.
On June 24, 1833, before a crowd of thousands of cheering citizens including Vice President Martin Van Buren, the famous frigate USS Constitution made history by becoming the very first vessel to ever enter an American dry dock, sailing into this stone basin for complete hull restoration under the command of Commodore Jesse Elliott. In the nineteenth century, giant steam-driven pumps drained millions of gallons of seawater from the dock in under two hours, resting the ship's keel on heavy oak blocks so shipwrights could scrape barnacles and replace copper hull sheathing. Dry Dock 1 remains fully operational today, still used by the United States Navy to perform periodic dry-dock maintenance and restoration on USS Constitution.
Looking down into the massive stepped stone amphitheater of the dry dock, the sheer monumentality of the masonry is awe-inspiring. It stands as a timeless monument to the brilliant engineering genius of Loammi Baldwin Jr., the father of American civil engineering. The extraordinary durability of this granite dry dock stands as a timeless masterpiece of early nineteenth-century American civil engineering and maritime stonecraft.
