ROCKLAND — The Strand Theatre, 345 Main St., will present an encore screening of “Rockland: A Maritime Heritage,” the new documentary from filmmaker Dale Schierholt, Saturday, Jan. 21, at 1 p.m. Admission is free and open to the public.

The film was cowritten with local author John Bird, based on his book “Rockland Maine: Rise and Renewal.” Joining Schierholt and Bird on the production is local video historian Wayne Gray. The film chronicles the history of the city of Rockland from its settlement as a part of Thomaston to the city it is today, by tracing the ebbs and flows of its evolution through its ties to the sea.

Bringing their vocal talents to the project are Joseph Coté who narrates the film and Mary Alice Bird who contributes readings of Rockland poets. The film was funded by local businesses Maritime Energy, The Free Press/The Courier-Gazette, and Ada’s Kitchen/Main Street Markets, with the Sail Power and Steam Museum serving as fiscal sponsor.

Running time is 62 minutes. For more information, visit rocklandstrand.com or call (207) 594-0070.
