I. Legends / Myths On The Origins And Source Of Its Name

Muntinlupa City is composed of nine barangays spread geographically between the two (2) political districts.  Barangay Tunasan is located in the First District with three other barangays namely Poblacion, Putatan and Bayanan.

  1. First Legend / Myth – During the mid 13th century, a group of Malays headed by a certain “Datu Puti” left Panay Island and traveled toward Luzon. With him are two datus, namely Datu Manaplo and Datu Malamig who proceeded to Manila.  But the natives who live in Manila were hostile, so they left Manila via the Pasig River.  When they reached Laguna de Bay, Datu Manaplo and his men decided to stay on the land area they found called Bagbagan and build their homes, while Datu Malamig, his father, proceeded to Calamba to settle.  It was said that in 1735, Bagbagan was changed to Tunasan.  On that same year, a document of ownership called Torrens Title was found, which registered Bagbagan in the name of Datu Tuna Asomal, son of Datu Manaplo.
  2. Second Legend / Myth – According to the old folks, Tunasan was a haven of hardened criminals and pirates (“Tulisan”), hence, it was called Tunasan. During those times there are Chinese merchants trading their goods enroute to the Pasig River where the Tulisan dwells.  A battle between the Tulisan and the Chinese merchants occurred.  The victorious Tulisan confiscated the goods of the Chinese merchants and buried them in ground.  This partly explains the fact for the treasures found by the residents when they dig to build their homes.
  3. Third Legend / Myth – According to legend when the Americans stock their Tuna Sardines in the area, the people hide them.  Every time they eat, they sent an errand boy to get some, (Totoy kumuha ka ng Tuna) the boy would ask “Where?” (‘san?) being so repeatedly at the passage of time, the term Tuna-san was coined which became the name of the place.
