The story of Mexico City began here, on the original islet the heart of the Aztec city. Its foundation stone is the centre of both the traza and the perfect circle of the Federal District after independence. The Plaza de la Constitucion, is a magical place. It is the world's second largest square

A historical showcase and a permanent market, a forum and a fair, this square is invariably buzzing with music and the banter of artists displaying their work, children flying kites, vendors setting up stalls and protest groups pitching their camps.

On each side it is bounded by the country’s institutions, monuments to its power, both past and present.
