On Saturday, July 20, visitors at Penobscot Marine Museum in Searsport will be able to explore the museum’s “Where in the World?” exhibit through special family-friendly activities including trivia, a scavenger hunt, speakers and more. All activities are included with museum admission. The “Where in the World?” exhibit features paintings of Maine cargo ships in foreign ports and the navigational charts that guided the way. Captains and owners commissioned paintings of their vessels as a point of pride to ensure a successful voyage. Today, these port paintings provide viewers with a tour of the ports as they looked in the early to mid-1800s. Navigational charts with hand-written course notations from the museum’s collections accompany the port paintings, putting the voyages of Maine sea captains into geographical context.
