The Portland Observatory was built in 1807 by Captain Lemuel Moody to serve as a communication station for Portland Harbor. Portland Observatory was one of the earliest marine signal stations in the United States, and it is the last known to survive. The Observatory's location on Munjoy Hill gave it a clear view of vessels approaching Portland Harbor. The Observatory contributed to the prosperity of Portland Harbor as a vital center of maritime commerce during the "Golden Age of Sail."

In 1794, the Delaware legislature authorized a lottery to fund the erection of ice piers in the harbor at New Castle. The ice harbor was designed to protect anchored ships from storms and ice. At the time, New Castle served as the principal winter port for ships from the Port of Philadelphia because ice on the Delaware River posed such a serious hazard to the wooden-hulled vessels. The harbor was the first of its type on the river and the last one to be maintained as the need for them declined. It served as a model for the other four harbors constructed in the area.
