Lucca is noted for its well-preserved ramparts (1561–1650) and has many fine 16th-century palaces, notably the Palazzo Pretorio and the Palazzo della Prefettura, the former grand ducal palace, now housing the National Art Gallery. There are several other art collections, libraries, and archives.

Lucca is a gem of Tuscany famous primarily for its perfectly preserved Renaissance-era city walls, which entirely encircle the historic center. Unlike many other Italian cities that tore down their fortifications to make way for modern roads, Lucca kept hers intact; today, the top of the wall serves as a lush, elevated public park and 4-kilometer cycling path. The city is also known as the "City of 100 Churches" due to its incredible density of religious architecture, including the stunning San Michele in Foro. Music lovers recognize Lucca as the birthplace of the great opera composer Giacomo Puccini, and his home is now a popular museum. Furthermore, the city is famous for its unique "Guinigi Tower," a medieval brick tower with ancient holm oaks growing from its rooftop. In 2026, Lucca remains a favorite for travelers seeking an authentic Tuscan experience without the overwhelming crowds of Florence, offering a harmonious blend of Roman street layouts, medieval towers, and a slow-paced, pedestrian-friendly atmosphere that feels like stepping back in time.
