The phrases you provided point to the Florence Cathedral, officially Santa Maria del Fiore, a landmark in Florence, Italy, famous for its dome engineered by Filippo Brunelleschi and for the adjacent Baptistery and Giotto’s Campanile. Key details you might find useful:

• Origins and design: Construction began in 1296 under the direction of Arnolfo di Cambio, with the church built on the site of the earlier San Reparata cathedral. The project was one of the great Florentine architectural endeavors of the late medieval period, evolving from di Cambio’s initial plan into a vast complex with three naves and a prominent central space that would accommodate the new dome.

• Dome and engineering: The original plans anticipated a massive dome, but it wasn’t completed for nearly 140 years. Brunelleschi’s innovative self-supporting double-shell dome was finally completed in 1436, marking a turning point in Renaissance architecture by solving the structural challenges of a stone dome without external thrust supports.

• Associated structures: The cathedral stands alongside the Baptistery of Saint John, noted for its ornate bronze doors, and Giotto’s Campanile, a separate free-standing bell tower that complements the facade and overall ensemble of the Duomo complex.

• Visit and overview: The site is commonly referred to as the Duomo di Firenze in Italian, and it remains the episcopal cathedral of Florence, with the Opera di Santa Maria del Fiore managing the site and activities associated with worship, tourism, and preservation.

If you’re looking for specifics, I can:

• Provide a concise timeline of major construction milestones.
• Compare the Florence Cathedral’s design and engineering with other contemporary cathedrals.
• Offer guidance for a visit, including must-see elements (duomo dome interior, frescoes, the dome lantern, the Baptistery, and the Campanile) and practical tips.
