History
Greater Portland Landmarks received two grants in 2022, one of which (from the National Trust for Historic Preservation) was to fund the search for sites in Greater Portland related to its Armenian American, Chinese American and African American heritage.

In 2024, the company sued the City of Portland in an attempt to prevent the demolition of the building, constructed in 1830, which was formerly the home of the Children's Museum and Theatre of Maine. The City Council had approved a plan to remove a historic classification from building, which stands in Free Street in Congress Square.
