[4] Cotabato City derived from PC Hill, which historically was used as a fort by natives in the area.

Cotabato City's name was derived from Kutang Bato or "stone fort".

Many of local law enforcement agencies hold office in the hill including the Cotabato City Police, and regional offices of the Philippine Drug Enforcement Agency, and the Criminal Investigation and Detection Group.
