The 1608 Virginia, America’s First Ship – Bath
America’s love affair with shipbuilding began in the spring of 1608, when the Popham colonists launched a 51-ft ship named the Virginia. The Virginia was seaworthy and sailed to England the following year, making it America’s first ocean-going vessel. A replica of the 1607 Virginia pinnacle ship now serves as a museum and floating classroom. At the Jane Stevens Visitor Center in Bath, you can see a faithful recreation of the four-century-old craftsmanship of the early Popham colonists.

Fort Baldwin – Phippsburg
Fort Baldwin was manned during both World Wars to protect the entrance to the Kennebec River and the Navy ships being built by Bath Iron Works. Its three separate six-inch gun batteries were intentionally covered with earth to hide them as much as possible. To reach the fort, take a gradual 10-minute uphill hike from a lofty position on the summit of Sabino Hill. There are scenic ocean views, and you can walk through the passageways of the three concrete batteries carved into the hillside.
