Caterina de Renzis Sonnino has expanded part of her family estate into the Castello Sonnino International Education Centre for researchers, educators and students committed to preserving environment and cultural heritage for future generations. Caterina de Renzis Sonnino's conservation and renovation work, and the revival of the winegrowing activity, have made the Castello Sonnino one of the most interesting educational sites and one of the finest producers in Florentine Chianti.
