The lemon houses, which are an incomparable historical and architectural legacy of Lake Garda, are vestiges of a laborious and productive past. Several major projects have been launched to preserve them.

The Comunità Montana dell'Alto Garda restored three còle terraces of the Pra dela fam lemon house in Tignale in 1985, and the city of Limone sul Garda restored the Castèl and Villa Boghi lemon houses in 2004. Restoration projects are underway or pending also in Toscolano Maderno and Gardone Riviera.
