I've come to think of September 11 as New York City appreciation day, a time to honor the sorrow and the past but also to celebrate the unique spirit of the city. Today's home, a prewar coop on the Upper East Side embraces both the grandeur and the spirit of this unique city. The home has a grand living room with 18th Century lightwood paneling and a French marble fireplace framed by two bookcases and a view overlooking 72nd Street. The dining room also has a fireplace and the library is lined with bookcases of red laquered wood paneling. The slim kitchen is equipped with a professional Viking stove and Traulsen refrigerator. There are four bedrooms total including a corner master bedroom overlooking James Church. The design scheme is whimsical in places and perhaps a bit fabric-centric but that's one of the things that is most endearing about New York City, it delights in eccentricity. This home is listed at $8.25 million. Pics after the jump or supersized in the gallery.

Our estate of the day has a fireplace so large that unless you are Shaquille O'Neal, you will feel tiny. The home is a Beaux Arts limestone townhouse on the Upper East Side of Mnahattan. The townhouse was created by John Duncan, the designer of Grant's Tomb. The home was built in 1902 and has nearly 15,000 square feet of space on six levels. Things to love about this home include the fireplaces, a large wrought iron staircase, ornate moldings and endless echoing marble. There are 17 foot ceilings in some areas and a living room you could throw one hell of a party in. The dining room overlooks public gardens and has floor-to-ceiling windows. It is listed at $31 million. After the jump, is that a tree in the library?
