His fortress of Peteroa built in 1556 was located near Teno "twenty leagues from the city of Santiago".
[1] A soldier in this campaign under Juan Godíñez, Alonso Lopez de la Raigada refers to the 1556 fortress as "Peteroa" and the camp where Lautaro was killed as "Mataquito" and also refers to "Peteroa y Mataquito" as separate places.
[2] Pedro Mariño de Lobera does not give a place name to the location of the 1556 fortress.
[3] The contemporary chronicler Alonso de Góngora Marmolejo gives no place names to either location in his account.
[5] The current town of Peteroa may be the vicinity where this fortress was located on the south bank of the Mataquito river and his second camp was located across the Mataquito river on its north bank.
