As others have stated, this is currently still being refurbished. But don't let that deter you - this was much more interesting than I was expecting, especially after visiting Monticello. The grounds are beautiful - there are miles of walking trails. If you're in the area and have some time, come early and take a nice walk. The tour guide was excellent and was able to answer every question asked of him. They have several archeological digs going on and they are very friendly to talk to.
