1 Best Sight in Rutland, Central Vermont

Completed in 1867, this 32-room mansion was built over the course of eight years by a Vermonter who married a British aristocrat. Within the opulent setting are 84 stained-glass windows (one inset with 32 Australian opals), hand-painted Italian frescoes, and 13 fireplaces. The place is magnificently furnished with European and Asian objets d'art. October evenings bring haunted castle tours.
