As depicted in the 1857 map found in the Philippine National Archives shows Ruinas de Tanauan, the first site of Tanauan is believed to be the present location of Talisay until 1754, then the violent eruptions submerged the whole ancient town of Tanauan. Residents of the said town moved to Sala (Bañadero). Then it settled on its present site naming it Tanauan in line with the celebration of the feast day of St. John the Evangelist, Sala then became a barrio of Tanauan. On a hill overlooking the lake, one can see ruins of a wall about 10-12 meters high that is believed to be the first stone church in Tanauan.
