The tallest landmark on the East End, the Portland Observatory, will open it's doors for free in celebration of Flag Day on Wednesday, June 14th. This historic building towers over Portland's peninsula offering sweeping panoramic views of the harbor and downtown.

The entrance fee is typically $10 for adults, $8 for students/AAA members/seniors, and $5 for kids, so a family could save some money on this super cool attraction by visiting on Flag Day.

The Portland Observatory and Portland Landmarks will offer additional events throughout the day, including a raising of the flags with Mayor Ethan Strimling, tours of the East End Cemetery, live music, and an architectural scavenger hunt.

You'll have the opportunity to learn about the history of the observatory including it's original purpose in the 1800s. It is the last standing maritime signal tower in the country, so there's plenty to learn about the observatory and Portland's long maritime history.

A full listing of events and times are available on the Portland Observatory Facebook page.
