 Later, the brick building was replaced with a larger one in stone that became a familiar landmark for its stately, central tower topped by a mansard roof.The property took up the block bounded by Fort (Broadway), 6th, Hill, and 7th streets.When St. Vincent's later moved to a new campus, the old building became US Army Headquarters, and in 1907, the large Bullock’s department store was built and operated here until 1983.
