Siena Cathedral Exterior

The Siena Cathedral (Duomo) is a masterpiece of Italian Gothic architecture with a black and white striped marble facade. The exterior and the surrounding piazza are free to admire. The interior is paid (combined ticket with the baptistery, library, and crypt). Budget travelers photograph the facade (one of the most ornate in Italy), explore the surrounding streets for free, and decide whether the interior ticket fits their Tuscany budget.
