Set atop San Francisco’s Nob Hill, railway magnate Mark Hopkins’ mansion was a display of ornate Victorian excess when it was completed in 1878. The man never got to see the finished product for himself because he passed away just before the job was done. Unfortunately, the building itself didn’t go the distance either as it was destroyed in the fire that followed the city’s 1906 earthquake and was never rebuilt. The site is now the location of the InterContinental Mark Hopkins San Francisco.
