Pozzo di San Patrizio (St. Patrick's Well), Orvieto (must see)

The Saint Patrick's Well, built in the 16th century, is designed by the renowned architect Antonio da Sangallo. It was commissioned by Pope Clement VII, who sought to ensure a reliable water supply for the town during times of siege.

What makes this well truly unique is its double-helix design. Unlike conventional wells with a single central shaft, St. Patrick's Well features two separate spiral staircases that wind around a central cylindrical core. This ingenious design allowed pack animals to descend to the water source while carrying heavy water vessels and then ascend without interference.

The well reaches a depth of approximately 53 meters (174 feet) and has a remarkably constant temperature throughout the year. This made it an ideal place for storing perishable goods and providing a cool escape from the scorching Italian summers. The well's exterior showcases impressive Renaissance architecture with its stone facades, decorative elements, and decorative friezes. It stands as a testament to the artistic and architectural achievements of the period.

St. Patrick's Well is not only a remarkable engineering achievement but also a piece of Orvieto's history. It served as a vital water source for the town during times of conflict and siege, ensuring its survival.

Today, St. Patrick's Well is open to visitors who can descend the winding staircases to explore its depths. As you descend into the cool darkness, you'll appreciate the scale and complexity of this engineering marvel.

The well is situated in a lovely park setting, surrounded by lush greenery and offering panoramic views of Orvieto and the surrounding countryside. It provides an excellent vantage point to admire the town's historic beauty.
