Portland Observatory

The Portland Observatory is a former maritime signal tower in Portland, Maine, now serving as a museum. It is the only surviving tower of its kind in the United States, dating back to 1807.
Metaphysically, the Portland Observatory extends into Three Portlands as a "shadow"; the name is due to the Observatory appearing as a shadowy ghost of itself.
