The Monument to the Heroes of Independence is the most noted of Mexico City's exceptional public sculptures and monuments. The "Angel" is both a landmark and homage to those who lost their lives fighting for independence. It's also a central stage -- along with the zócalo -- for many of Mexico City's celebrations and demonstrations. Set upon a tall marble and Italian granite base, the golden angel is an important and easily discerned guidepost for travelers. A creation of Antonio Rivas Mercado, the 7m-high (23-ft.) gold-plated bronze angel, cast in Florence, Italy, was completed in 1906 at a cost of $2.5 million. The monument's height is 45m (148 ft.). It was renovated in 2006.
