Main Street School

Why it's listed
Main Street School in Port Washington, New York, is a brick Georgian Revival school crowning the highest hill in the hamlet, overlooking Manhasset Harbor. Designed by local architects Frank Cornell and Ralph Dusinberre and built by Smull and Walsh, it was finished in 1909 after the newly consolidated school district bought a 5.5-acre site. The two-story building has stone detailing, a steep gable roof, five round-headed dormers and a cupola with four clock faces. Rapid population growth, driven by the arrival of the railroad and Northern Boulevard, soon crowded the classrooms, so Cornell added two three-story wings in 1917 that preserved the building's symmetry. It first served as the town's twelve-year school and later became an elementary school. Because Port Washington has no town hall, the building also acts as the community's most prominent civic landmark. It was listed for its architecture and its long role in local education.
Significance in brief: The nomination presents it as a distinguished, monumentally scaled example of early twentieth century Georgian Revival architecture and the most prominent civic landmark in a hamlet with no town hall of its own. It is the oldest extant school in Port Washington and has been tied to local education since 1909.

What listing means for this property
For a publicly owned building or structure, listing mainly matters when federal funds, permits or licences are involved: projects then go through Section 106 review so effects on the property are considered. Listing also strengthens applications for preservation grants and, for leased income-producing uses, can enable the federal rehabilitation tax credit.
