Officially called the Cathedral of Santa Maria del Fiore, this Florence Duomo really outlines the history and taste of the city in art. Construction in the Gothic style began in 1296, and completed by Filippo Brunelleschi in Renaissance style in 1436. This marvel of engineering, still representing the largest brick dome ever constructed, remains a testament to Florentine ingenuity. Visitors will be impressed, right from the outset, by this magnificent Duomo that sports polychrome marble panels in shades of green, pink, and white. On entering, one will find that the outer structure evokes an interior of great openness, as it is adorned with frescoes on its walls and tinted glass works on the windows.
