market. Hotel Regis The Hotel Regis was built in the beginning of the 20th century as a luxury hotel in neo-Classical style. It had its own cabaret, gourmet restaurant and a small but luxurious cinema with wide reclining armchairs. It was located at the corner of Balderas and Avenida Juárez in the historic center and completely collapsed within moments of the quake. Shortly after its collapse, it began to burn due to a gas leak, which made it extremely difficult to rescue survivors. Nothing survived of the hotel. The space is now the Plaza de la Solidaridad park. The Museo Mural Diego Rivera on the north side of the park houses a mural by Diego Rivera which was originally housed in the huge Hotel Del Prado across the street. That hotel was irreparably damaged in the earthquake and subsequently demolished. Apartment complexes in Tlatelolco There were two apartment complexes in the area of the city called Tlatelolco to the north of the historic center that became major scenes of disaster, the Conjunto Urbano Nonoalco Tlatelolco and the "Multifamiliares Juárez" near the Metro Centro Médico. Together, these apartment complexes were a large percentage of the 30,000 units lost, with the city losing about 30% of its living space. Nonoalco Tlatelolco was located on Paseo de la Reforma Norte #668, covering an area of about . It had 102 buildings with seven medical facilities, twenty-two schools and about 500 small businesses, serving the 80,000 people who lived there. Constructed under the presidency of Adolfo López Mateos, it was considered the most important complex of its kind in the country. In the Conjunto Urbano, two of the three modules of the building called "Nuevo León", at thirteen stories tall, completely collapsed, while the other one was severely damaged. In other buildings, dozens of people terrified by the event jumped from high windows to their deaths, trying to escape. People became trapped in stairwells, elevators and their apartments without any way to contact the outside world. At the collapsed building, lines of 50–100 people passed rubble by hand and buckets, trying to reach victims. During these rescue efforts, a nearby building, called Oaxaca, began to creak noisily, causing everyone to run and abandon the site temporarily, but it did not collapse. All the buildings suffered damage but along with the collapsed Nuevo León building, buildings such as those called Veracruz, Coahuila, Zacatecas, Oaxaca, Puebla,
