Puerta Piazza Castello is a spectacular castle entrance located in the hilltop village of Barolo in Italy's Piedmont region. The turreted brick structure stands guard at the edge of the historic village and serves as the main thoroughfare for visitors and local residents. The arched passageway, which is currently a protected historical landmark, is lined with colorful flowers and is a popular spot for photography. Take time to explore the picturesque square and its many art galleries, cafes and wine shops. Climb up the castle's winding staircase to enjoy breathtaking views of the village and rolling hills of the surrounding countryside.
