シエナ大聖堂
The façade of Siena Cathedral is one of the most fascinating in all of Italy and certainly one of the most impressive features in Siena. Each of the cardinal points (west, east, north, and south) has its own distinct work; by far the most impressive of these is the west façade. Acting as the main entryway to the Duomo proper, it boasts three portals (see Portal (architecture)); the central one is capped by a bronze-work sun.
