A look inside the walls of the 11th-century castle on Marco Simone Golf & Country Club – PGA TOUR

The castle, which is accessed by passing through a series of three different security gates, contains about 50 rooms, many of which feature Renaissance-era frescoes. It was named Marco Simone for the son of a 15th-century owner, Simone dei Tebaldi, who oversaw a massive restoration after centuries of invasions.
