Marjorie Post, heir to the General Foods fortune, bought this stunning mansion in 1955 and soon decided it should be a museum open to the public. She filled the house with beautiful furniture and art from 18th and 19th century France and Russia. She landscaped the estate's 25 acres with beautiful gardens and woodland paths.

This beautiful manor below Pena Palace is worth a visit, primarily for its remarkable grounds, sprinkled with winding paths, tunnels, secret passages, and more to explore.
Ireland
This is a giant neo-gothic country mansion built in the 1860's. Later it became a boarding school run by benedictine nuns until the school closed in 2010. You can visit some open rooms downstairs (nuns still live upstairs). The main reason to visit however is a view from the lakeshore, Pollacapall Lough, and possibly a stroll through the gardens and to see the Gothic Church.
