Center of the Archipelago, Mother of all Data (Luzon datum of 1911)

I was amazed by the information I have learned, couple of months ago, that there was a land mark, historical land mark actually, situated near the place where I grew up. During my early years in my hometown, I haven't heard anything about it. I know the place actually, but I didn't know that there is such thing like this which can be found in the place. Even my parents and my grandparents don't talked about it. My teachers in school don't informed us about it. Maybe it is because no proper documentation has been made about this thing.

What I am talking about is the Luzon Datum of 1911 which is actually celebrating it centennial this year.


Luzon Datum of 1911 is a Geodetic Center of the Philippines. It was established by the United States Coast and Geodetic Survey (USCGS) now National Oceanic and Atmospheric Administration (NOAA). A geodetic marker drilled in a cubic meter of diorite rock on a mountain top located at the boundaries of Argao, Hinanggayon, and Silangan at Mogpog. 13°33'41"N, 121°52'3"E


This important geodetic point marker serves as point number one for all map markers in the country at first level accuracy.

I can't believe that a thing like this exist in the place where I live. And in the celebration of its 100 years of existence the local government put up a Historical Centennial Marker in the place. They also put up a gazebo for those who will find it as a tourist spot.

I'm sure this is one thing, a Marinduqueno like me must be proud of.
