Torre del Caballito, Office skyscraper on Paseo de la Reforma, Mexico City, Mexico

Torre del Caballito is a 135-metre office skyscraper on Paseo de la Reforma, its narrow rectangular slab clad in dark reflective glass panels set in a uniform grid. It has 34 floors with 60,000 square metres of office space and a floor-to-ceiling height of 3.62 metres. A small pale emblem sits near the top, and a red aircraft warning light is mounted on the roof.

The structure was originally designed in 1980 as a Holiday Inn hotel, but economic pressures and the devastating 1985 earthquake prompted a change in plans. It was completed in 1988 as an office building instead.

The tower's name comes from El Caballito, the yellow abstract sculpture by Enrique Carbajal (Sebastián) standing beside it, which honours the old equestrian monument moved from this spot to Plaza Manuel Tolsá. The building itself houses the central local administration of the Tax Administration Service (SAT).

The tower has nine high-speed lifts running at 6.3 metres per second, fitted with seismic detectors that stop the car at the nearest floor when the ground moves. Six underground parking levels serve the building, and the offices of the Tax Administration Service (SAT) for the city centre occupy part of it. It stands at Paseo de la Reforma 10, beside the yellow sculpture El Caballito.

The tower's lifts carry seismic detectors that stop the cabin automatically at the nearest floor when they sense ground movement, letting passengers get out. A building management system ties together the electrical, plumbing, lift and fire-protection equipment and also controls the lighting. The glass panes are 2.1 centimetres thick and the structure is calculated to resist winds of 257 km/h.
