The McAllister Hotel was a ten-story high-rise hotel in Downtown Miami, Florida. It opened on December 31, 1919, and until 1925, was the tallest building in Miami. It was demolished in 1988, and the site is now the home to 50 Biscayne built in 2007 at 554 feet (169 m). The McAllister Hotel is considered one of Miami's first skyscrapers and was a city icon until its demolition. It was designed by Walter De Garmo. The architect was Frank Valentine Newell.
