The Portland Company, the city\u27s oldest industrial concern, was founded in 1846

The Portland Company, the city\u27s oldest industrial concern, was founded in 1846 and has been owned by the same family nearly the entire time. The largest tenant is Portland Yacht Services, operated by Phineas Sprague Jr., who owns the 10-acre waterfront property. He would like to sell the property, maintain his company on the site and have the future developer preserve as many of the historic brick buildings as possible. At one point, luxury Knox automobiles were made there. With details on how Phineas Sprague eventually took ownership of the land from his family, and his hopes for the Maine Narrow Gauge Railroad & Museum, which operates there now through his efforts. The property is the largest piece of property in private hands east of Casco Bay Bridge
