The "Palacio de Bellas Artes", or Palace of Fine Arts, is a cultural centre in Mexico City that was built between 1904 and 1934. The palace contains a large theatre, concert hall, museum of popular arts, and halls and galleries for paintings and other works of art.
The Mexico City Metropolitan Cathedral was built using the stones that remained from the Templo Mayor which was destroyed in the 1500s by the Spanish. This is one of the largest and oldest cathedrals in the Americas so it’s an impressive albeit tragic monument.
Often referred to as the Central Park of Mexico city, the "Bosque de Chapultepec", or Chapultepec park, is one of the largest city parks in the western Hemisphere and is actually double the size of Central Park, and just like Central Park you could spend a whole day here and still not have seen it all. There's a zoo, multiple museums, a botanical garden, a recreational lake, monuments to Mexican patriots and international heroes, plenty of photo ops, and even an archaeological site, Montezuma's Baths. Make sure to visit Chapultepec Castle while you're here!
Tenochtitlan was the ancient capital of the Aztec empire that flourished between A.D. 1325 and 1521. At the time of the Spanish Conquest, the Aztec capital city of Tenochtitlan was among the largest cities in the world, with perhaps as many as 200,000 inhabitants. It was largely destroyed by the Spanish conquistador Hernán Cortés after a siege in 1521, and modern-day Mexico City now lies over much of its remains.
