Piazza Duomo in Lecce stands as the religious and artistic core of the city, showcasing one of the most remarkable examples of Baroque architecture in southern Italy. Initially known as the "Cortile del Vescovado," it was a secluded area reserved for the clergy until the 18th century when it was opened for public enjoyment.

The square's current layout originates from the 17th century, commissioned by Bishop Luigi Pappacoda, who enlisted architect Giuseppe Zimbalo to reimagine the space. This renovation resulted in an extraordinary Baroque architectural marvel, where the finely sculpted Lecce stone takes center stage.

The Duomo of Lecce, which lies within the square, is dedicated to Maria Santissima Assunta. Originally constructed in 1144, the church underwent a complete reconstruction in 1659 led by Giuseppe Zimbalo at the behest of Pappacoda. Zimbalo designed two facades: the primary one facing the square is relatively modest, while the secondary facade, which faces Via Vittorio Emanuele, is intricately adorned with typical Baroque details. Inside, the cathedral features three naves and is home to significant artistic treasures, including a beautifully crafted wooden ceiling and numerous valuable paintings.

Adjacent to the Duomo stands the impressive Campanile, soaring to 72 meters, which dominates the skyline and offers breathtaking views extending to the Adriatic Sea. Also designed by Giuseppe Zimbalo and completed in 1682, it is celebrated for its elegant architecture and harmonious proportions.

The square is flanked by the Episcopal Palace, the bishop's residence, which was built in the 15th century and expanded over the following centuries. The palace showcases a magnificent portico supported by columns adorned with Baroque decorations, complemented by richly ornamented rooms that reflect the significance of ecclesiastical authority in the region.

Facing the Duomo is the Palazzo del Seminario, constructed between 1694 and 1709 based on designs by Emanuele Manieri. Its elegant facade features a central portal and windows embellished with Baroque motifs. Inside, the Diocesan Museum preserves a wealth of sacred art and historical artifacts from the Diocese of Lecce.

Piazza Duomo is a distinctive space, enveloped on three sides, creating a serene and intimate ambiance. At night, the artificial lighting accentuates the beauty of the Lecce stone decorations, imbuing the square with an enchanting allure. Today, it is one of the most frequented locations in Lecce, symbolizing the city’s historical and artistic heritage as well as the Baroque style for which Lecce is renowned.
