The mansions of Newport -- originally called "cottages" -- were built as summer homes in the 1850s to 1900 by wealthy tycoons of New York and Philadelphia. Now, these massive houses, including the spectacular Rosecliff, Marble House, the Breakers, the Elms, Rough Point, and more, are open to the public, offering fascinating and informative tours. Special events, parties, balls, and performances, are presented during summer, fall, and the Christmas season. The magnificent Newport Flower Show takes place yearly at Roseclilff.
