The Stewart Building at Kempner & Mechanic, Historic Strand District in Galveston, Texas. This renaissance revival building, designed by architect Eugene T. Heiner, survived the devastating 1900 storm. It's details are stunning, to say the least, and the history is also very interesting. More information about the history of this building and Stewart Title can be found here.
