The Atlantic House (often called the A-House, even in its own advertisements) in Provincetown, Massachusetts is a drinking establishment that has been in continual operation on the tip of Cape Cod for over two centuries. Having been an openly gay-friendly establishment for half a century and discreetly so for perhaps twice that long, the Atlantic House is a contender for the oldest gay bar in the United States. Frommer's calls it "the nation's premier gay bar".
