The Castèl lemon house, which is northwest of the old town center and stands against the rocky wall of the Mughéra mountain, is just a portion of the large lemon grove that once stretched from the Mura valleys, Via Pozze and Via Castello to the Màndola valley. The garden, which covers an area of 1,633 square meters, is divided perpendicularly into two parts by the cùen dela Marchesàna, on which the main casèl is built on several levels.

It extends to the south, in part, on a single terrace and on three in another section. To the north it is divided on four còle terraces that border to the north with the Valèt del Castèl, on which another small casèl is built.
It was built in the early 18th century, but has clearly undergone remodeling over the years. The date "April 15, 1786" can still be seen on a water trough, which might refer to the construction of the structure itself or of the irrigation channels on the terraces. Other projects raised or moved the pillars and increased the surface area and the number of levels of the cas'èl.
Over the years, the lemon house was owned in turn by the Amadei, Bertoni, Patuzzi, and, in the 19th century, the Girardi and Polidoro families. On June 19, 1926, Giuseppe Segala (1889 - 1975) bought it after returning from the United States, where he worked as a miner. In January 1995, the city of Limone sul Garda bought the lemon house.

It has undergone renovation three times: during the first project, completed in 1997, a wall was built, a sparadòs and cantér were replaced, and the còle terraces were cleaned. During the second project in 1999, the roof of a casèl was repaired. During the third, in 2002-2003, two casèi and two còle were restored thanks to contributions from the Lombardy Region through the Plan of Rural Development 2000 - 2006.
The main cas'èl connects the terraces and serves as a museum and educational center. All the còle terraces have irrigation channels for the lemon trees. The water came from the San Giovanni Torrent through the Calmèta duct built in the early 18th century. The lemon house, which was inaugurated on July 22, 2004, has more than seventy citrus trees (citrons, lemons, sweet and bitter oranges, chinotto oranges, bergamots, grapefruits, tangerines and kumquats).

The Castèl lemon house is open daily to the public, from 10:00 a.m. to 10:00 p.m., from April to October. For other months or for more information and reservations, please call 0365-954720 during office hours.
