• Freeport Historical Society introduces its new Heritage Trail with a ceremony at 4:30 p.m. Tuesday at Old First Parish Meetinghouse and Burial Ground at Lower Main Street and Meetinghouse Road.

The 17-sign, self-guided trail directs visitors to significant spots in Freeport history.

State historian Earl Shettleworth will speak at Tuesday’s event. The trail reinforces the idea that Freeport has a deep and culturally rich history as a seafaring community and once-thriving industrial town. It’s known today primarily for its shopping.

The signs include historical photographs and text that tell stories of notable people, significant structures and landscapes and key events. The Freeport Historical Society also has created a podcast for each site, narrated by local folks.

To learn more about the trail, call 865-3170 or go online to freeporthistoricalsociety.org.
