Safest Place To Be During A San Francisco Earthquake - Roadside Attractions on Waymarking.com

Since it withstood the shaking, it might be presumed to be a safe structure to be around in another earthquake. Excerpted from the San Francisco Art Commission:

Standing silently on the north shore of Lloyd Lake in Golden Gate Park, Portals of the Past consists of the remains of the Towne mansion, a lavish example of Colonial Revivalism designed by the architect Arthur Page Brown for Alban Nelson Towne, the Vice President of Southern Pacific. The mansion, which stood at 1101 California Street (now the site of the Masonic Auditorium) was destroyed in the earthquake and resulting fire of 1906. The structure’s marble-columned portico was left standing, however, inspiring the iconic photograph by Arnold Genthe in which the entranceway, silhouetted by moonlight, rises from the surrounding ruin. Donated by Mrs. Caroline Towne in memory of her husband, the portico was presented by former Mayor James Phelan to the Park Commission and placed by John McLaren in 1909 in Golden Gate Park.
