At the southern end of the broad avenue (´viale della limonaia´) which leads one back to the Pitti Palace, is the ´Lemon House´. Designed by Zanobi del Rosso, who is also responsible for the Kaffeehaus, it was erected in 1777-78 as part of Peter Leopold's renovations of the Garden. The building retains the colorful original rococó stucco which once characterized many Florentine structures. It was built where the Medici once kept a menagerie of rare animals. The Limonaia was intended to house rare and interesting citrus plants and today it still houses a collection started by the Medici. The Medici held citrus in high regard, for their reputed medicinal and therapeutic qualities as well as for their beauty and uniqueness of certain citrus plants.
