Flemington is a perfect example of a 19th-century county seat, boasting so many well-preserved historic buildings that the town looks remarkably like its past self at 100, or even 150, years ago. Flemington has one of the best collections of Victorian and Greek Revival buildings in the country, with more than 60 percent of the borough listed on the National Register of Historic Places. Plus, the town has a working steam train that runs between Lambertville and Flemington, adding to the overall old-timey feeling. At just a touch over one square mile, Flemington is what New Jerseyans calls a "doughnut hole town," as it is completely surrounded by Raritan Township — the encircling doughnut — and the two municipalities are often grouped together. Raritan Township has a larger population and many single-family houses on large lots, while Flemington offers some condos, as well as historic homes, within a walkable core.
