Km.0 or Kilometer 0 is a distance reference to all other places in the Philippines.
Most Filipinos know this is seen at Luneta Park, particularly in front of Rizal Monument. But only a few know that there is also a Mindanao KM.0 which can be seen at the Islamic City of Marawi in Lanao del Sur.
Manila, KM.0
This is the reference point of all the places in the Philippines. The next time you travel, look out for the yellow road markers along the way.
Mindanao, KM.0
This is the original reference point of all roads in Mindanao.
It is a Saturday and if you don’t have anything to do, why not review the past PHOTO DUELS.
Trivia 1: When I do my out-of-town long runs before, I make use of these yellow markers on the road to measure the distance I ran.
Trivia 2: The original KM.0 is not in Luneta but in Intramuros. Learn more about it on the article: 10 New Learnings in Intramuros

Ayyy! Marawi City pala ang Ground 0, este Km 0 sa Mindanao hehe… Interesting… I wonder kuya bakit hindi ang mga tier cities like Davao of CDO :p
because marawi is a great islamic city even before DAVAO or CDO became big cities
Premonition after 4 years it became a totally distructed city. A ground zero indeed?
