This was an unexpected surprise when planning my trip. The building has been nicely restored, there are many displays and reconstructions, and the grounds are great. The displayes include not only furniture and art but also replicas of many of da Vincis inventions. Be sure to check out the chapel. The grounds are great for wandering. They include working copies of many of his machines as well as lakes, creeks, places to sit and contemplate. Look north over the building to the chapel on the top of the hill at Chateau Amboise to see Leonardos final resting place (then go to the Chateau and look back towards this red building to see Leonardos last residence from his grave). Only down side is that there is not photography allowed inside the house. On the walk to this site (there is really no parking; so, walk there) look at the troglodyte houses built into the hillside.
