Portland Observatory
One of the earliest maritime signals to be built, the Portland Observatory is the only remaining signal tower in the US.
Please check our website for current hours, tours, and admission. A typical season runs seasonally between Memorial Day and Indigenous Peoples' Day. The tower is closed on July 4 every year. Tours of the Observatory offer in-depth history of the builder, Captain Lemuel Moody, the purpose of the signal tower and its impact on Portland Harbor, as well as the history of the physical structure.

POV: The perfect Maine summer day. Live music, free admission, and great weather. Come visit the Portland Observatory today as we celebrate Flag Day! We're here until 3:30.

Join us in ONE week for:
Portland Observatory Flag Day Celebration
Sunday, June 14 | 10:00 AM - 3:30 PM
Portland Observatory | Free Admission
Come celebrate Flag Day the Portland way, at the last remaining maritime signal tower in the country!
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.

No, you don't need to adjust your glasses, but you do need to save the date!
What you're seeing is a historic image of the "Faith" statue in Hallowell—brought to life in 3D. This is just one glimpse of what awaits you at Portland Unlocked, Greater Portland Landmarks' upcoming fundraising event.
On Tuesday, June 23, Maine State Museum Director Bernard Fishman will take you on a journey through rare stereograph images from the mid-to-late 1800s and early 1900s—photographs you've likely never seen, presented in breathtaking 3D. The centerpiece presentation, "Historic Maine in 3D", happens inside the magnificent The Portland Masonic, one of Portland's most storied and long-hidden gems, in its original plush velvet seating, surrounded by Masonic murals and woodwork that have to be seen to be believed. And getting there you'll ride elevators of the same manufacture as those aboard the Titanic.
Want to go deeper? Only 50 VIP tickets are available for an exclusive private tour and a special reception with Bernard in the stunning Billiards Room — crystal chandeliers, leather couches, and yes, billiards tables included. VIP tickets go on sale May 26, with general admission following on May 28.
This is a rare chance to step inside Maine's past—literally—while supporting the organization that works to preserve these irreplaceable spaces. Don't miss it.

Planning your trip to the Observatory and can't quite wait until we open on May 23rd? Check out "The Last One Standing," a documentary about the Observatory created by SMCC students Noah Bonnell, Keegan Pierce, Kyle Scott, and Abe Huff.
