Biltmore, North Carolina. This is as close that you can get to visiting a French Renaissance château in North America. The grand house was built in the late nineteenth century for the ultra-rich Vanderbilt family, in the style of the châteaux of the Loire Valley; and though it was built three centuries after the French originals, it is faithfully in their spirit. It is still owned by a Vanderbilt family company, and is open to the public.
Castello di Amorosa, Napa Valley, California (photo top of page) can best be described - like the castle at Guédelon in France - as a modern medieval castle. It was completed in 2007 by owner Dario Sattui, whose dream was to recreate an Italian winery in California, complete with medieval Italian castle. The castle was hand built by craftsmen using local stone and antique bricks imported from Europe. Among its 107 rooms is a great hall with a 500 year-old Umbrian fireplace, and wall paintings by Italian artists; and underneath the castle are some of the largest vaulted wine cellars in North America. Privately run - open for visits and wine tours.Hearst Castle. A bit older, and also in California, Hearst Castle, in San Simeon, was completed in 1947 by media mogul William Randolph Hearst. Hearst had brought back from Europe a large number of architectural antiques, including whole buildings, which were incorporated by Hearst's architect Julia Morgan. The overall style is Southern Spanish Renaissance, and the castle itself is as much a village as a castle. Today it belongs to the State of California, and is open for visits.

Château Laroche - Loveland Castle, Ohio. This is a very fake and quirky, but somehow convincing, stone and brick fortified medieval castle that was built in the mid twentieth century by a rather eccentric medievalist called Harry Andrews. It is now open as a not-for-profit museum.
Lynnewood Hall - Elkins Park, Pennsylvania. Currently undergoing restoration. Designed by architect Horace Trumbauer, this lavish 110-room Neoclassical Revival mansion was built at the end of the 19th century for industrialist Peter Widener.
