The city of Lucca in Tuscany, Italy, is famous for its medieval architecture and intact city walls. Yet among all of its exquisite buildings one stands out. The Torre Guinigi towers over the city. At the top of the 44.5 meter (146 feet) high tower is something of a surprise - a garden containing, of all things, oak trees. High above the city this small wood has provided a haven of peace for centuries.
