The obelisk was built in 1948 . It replaced the original obelisk built shortly after the 25 January 1899 fire , but which was destroyed by the 1918 San Fermín earthquake . The obelisk was erected by a city board consisting of Jaime L. Drew , Antonio Arias , and Antonio Mirabal . This monument is different from the obelisk/tomb built in 1911 , and dedicated to the same men , and which stands at the Cementerio Civil de Ponce ( Ponce Civil Cemetery )
