Palazzo Farnese, with its magnificent Italian gardens surrounded by the green Cimini hills, is one of the most beautiful examples of Renaissance architecture in Europe. The building, with its distinctive pentagonal shape, was commissioned by Alessandro Farnese (who became Pope Paul III). The palace is famous not only for its pentagonal shape but also for its spiral staircase or “Scala Regia”, its circular courtyard, its interiors filled with large frescoes and its Italian gardens.
