Walk down Main Street in Sag Harbor and you're walking through a whaling port. The captains' houses, the Custom House, the Old Whalers' Church and the Greek Revival mansion that now holds the Whaling Museum were all built on the money that came home in barrels of whale oil. Here's the short version of how a small harbor on the South Fork became one of the great whaling ports of the world — and what you can still see today.
From "Harbor of Sagg" to international port
Sag Harbor first appears in Southampton town records in the early 1700s, and English settlers began building there around 1730. By the mid-1700s the harbor was shipping farm goods from the surrounding countryside to the West Indies, and local crews were going after whales.
During the Revolution the British held the harbor. In 1777, Colonel Return Jonathan Meigs led patriot raiders across Long Island Sound in whaleboats, attacked Sag Harbor and burned a dozen British vessels.
New York's first port of entry
By the time the new federal government organized itself, Sag Harbor had more square-rigged ships in foreign trade than the Port of New York. On July 31, 1789, the First Congress designated it an official port of entry, and George Washington appointed Henry Packer Dering to run the customs office. Anyone shipping goods to Long Island had to declare them here.
The village became a regional hub: Long Island's first newspaper was printed in Sag Harbor in 1791, and the Custom House doubled as Long Island's first post office.
The whaling boom
From roughly 1760 to 1850, whaling drove the economy. Sag Harbor ships sailed for months or years at a time, and crews were remarkably diverse — Native American, African American, Cape Verdean, Pacific Islander and New England sailors worked side by side. In 1797 a shipyard opened on Bay Street to build and outfit whaling vessels; today it's still working as Sag Harbor Yacht Yard.
The industry peaked in the 1840s, when the wealth showed up in the architecture. The Old Whalers' Church was completed in 1844, and in 1845 whaling merchant Benjamin Huntting II built the columned Greek Revival mansion designed by Minard Lafever.
Why it ended
Several blows landed at once. The 1849 California Gold Rush lured crews and even whole ships west, petroleum began replacing whale oil for lighting, and a series of great fires — including the devastating blaze of 1877 — destroyed much of the waterfront. Sag Harbor turned to manufacturing, then to summer visitors. The Sag Harbor Yacht Club was founded in 1899, signaling the shift from working boats to pleasure boats.
