The Windsor Tower (Spanish: Torre Windsor) was an office building in the financial center of Madrid, Spain. Built in 1979, it was 106 m (348 ft) high and had 32 floors of which 29 were above ground level and 3 below, thus ranking it as the eighth tallest building in Madrid (and 23rd in Spain). The building was gutted by a huge fire on February 12, 2005, and partially collapsed; it has since been demolished.
