Rising from lush landscape like a lemon from its tree, this pale yellow villa built in 1624 was once the summer residence of Count Cosimo Bernardini. Citrus and herb gardens, ponds and brooks, and grand cypress trees surround a classic interior with terracotta floors, a library, and high painted ceilings. Dip in the pool, lunch beneath the vines, and play tennis 1.5 miles away while the chef preps dinner.
