The Stony Brook Post Office is also home to the Mechanical Eagle that resides on its pediment, where it flaps its wings every hour, on the hour (from 8am – 8pm) – as it has done so since 1941, welcoming thousands of visitors to the village’s specialty shops and restaurants. The eagle was hand carved and its wings span 20 feet. The post office, a traditional hub of community activity, was the core of Mr. Melville’s original vision and project – his “living Williamsburg.” It is located in Harbor Crescent, where a series of connected shops overlooks the Village Green. The Stony Brook Post Office is the site of The Ward Melville Heritage Organization’s holiday tree lighting and has become a premier wedding photograph location for generations of the area’s brides and grooms.
