 Situated at the northernmost sector of Marikina along the concrete highway that leads to the towns of San Mateo and Montalban (Rizal), Barangay Nangka was the most rural among the city's barangays.It started as a small settlement built by two pioneering families and later evolved into a flourishing community largely due to a river, which is the barangay's namesake, that bilaterally cuts through Marikina and San Mateo, in Rizal Province.Named after the jackfruit, Barangay Nangka was created under RA 260, which was approved by Congress on June 21, 1959.
