The Portland Observatory has been keeping watch over Casco Bay since 1807, and on June 14th this National Historic Landmark and National Historic Civil Engineering Landmark opens its doors to the whole community, completely free of charge. Spend as much or as little time as you like with self-guided tours running all day, and friendly docents will be on hand to share the stories behind this one-of-a-kind structure and answer every question you can think of.

Live banjo music and sea shanties by James Weitlauf will keep the good vibes going throughout the day, and there are activities for kids to enjoy as well. And if you think you know what this tower is, think again: come find out once and for all why the Portland Observatory is absolutely, definitively NOT a lighthouse. Free and open to the community. No registration required. Just show up and explore.
