Luxury home once birthplace of opera

Paolo and Gabriella Mazza of Florence, Italy combined a work project with a new home when they purchased La Camerata, as the 3,444-square-foot (320 square meters) theater, believed to have been designed by Renaissance architect Filippo Brunelleschi. (slideshow)

The couple spent four years and four million euros to turn the building into a luxury home. The theater, part of a 15th-century palazzo purchased by Mazza's company, "was a meeting place for the Florentine Camerata, the group of 16th-century musicians and theorists credited with inventing opera."
