What are those high pillars soaring skywards, all lined up, enclosed with white stone walls on three sides? They are remains of lemon orchards that Goehte was struck by two centuries ago "...We passed by Limone whose gardens, terraced and plated with lemon trees, have a rich and beautiful look..." (from "Italian Journey"- 1786). Those lemon gardens were lemon houses which date back to the 13th century when citrus cultivation was introduced on the Lake Garda.So these characteristic big houses started up, suitable for protecting The valuable plantations against the possible rigours of winter.
Lake Garda therefore became the most northerly area of the Earth where citrus fruits were produced commercially.In spite of their decay, the only ones of their type, are still left as witnesses of a very flourishing age for the economy of Lake Garda where citrus growing was considered to be a real industry.
