The Limonaia represents the typical structure of the lemongarden of Lake Garda.
Its structure is absolutely unique in its kind and had the scope to concur the cultivation of these citruses in a geographical position border of the Alps. The lemongaerten “Limonaia del Castel” testifies the importance in the "Coast of the Lemons" (from Salò to Limone) of the cultivation of lemons, which represented, until the end of `800 century, the first source of yield for this part of Lake Garda.
The cultivation of lemons was already known from the '300 but becames a flourishing industry only from the `700 when the family Bettoni of Bogliaco constructed immense greenhouses in Bogliaco and Limone and constituted in north-oriental part of Europe the company "Francesco Bentotti" in the aim to manage the export of lemons. Thanks of this initiative the Lake garda becames the most northern zone in the world for cultivation of the citruses: to 46° the degree of latitude nord.
From 1855 began the slow decline of the cultivation of the lemons: the "Gommosi" (the greater disease of the lemon-trees), the competition of the more economic lemons from the southern regions and the discovery of synthetic citric acid were the main causes.
