The John Rankin House at 440 Clinton Street is one of our faves. Here’s what the New York Community Trust Plaque, mounted in 1971, says:

When it was built, about 1840, this mansion was surrounded by farmland and commanded a magnificent view of the Upper Bay. John Rankin, the original owner, was an affluent Brooklyn merchant. Little altered since its construction, and retaining its original ironwork, this building is one of the finest Greek Revival residences in the City, with full height brick pilasters, symmetrically placed windows and a handsome central doorway.
