Chapultepec Uno R509, previously Punto Chapultepec, is a skyscraper in Mexico City at the corner of Paseo de la Reforma and Río Ródano street, immediately west of Torre Mayor. Chapultepec Uno is Mexico City's third tallest building upon completion at 241m and 58 stories high.[1] [2] Part of the tower is occupied by the Ritz Carlton hotel, which was opened on October 28, 2021.[3]
In 2005 there was a project to remodel the existing towers on the lot, Torre Reforma 509 and Torre Reforma 506,[4] [5] but it was not successful. In 2009, Serrano Arquitectos planned to build a skyscraper 303m and 69 floors high but in 2010 the project was cancelled in favor of a shorter tower.[6]
