ICON brings contemporary luxury to downtown Houston.Every great city has a landmark hotel that speaks volumes about its history and embodies a sense of place.  In Houston, that landmark is the Hotel ICON, an exclusive member of Marriott's Autograph Collection, located in the heart of downtown at the confluence of dynamic business, theater, legal and sports districts. Originally built in 1911 as the Union National Bank Building, Hotel ICON thoughtfully balances irreplaceable period detail, grand neoclassical architecture and dynamic, contemporary appointments.  Intimacy, sumptuous surroundings and modern efficiency lure the well-heeled traveler as well as the local movers and shakers.
