Manila is apart of the National Capital Region, there are 17 cities in this and each elect a mayor for the council.
Manila occupies the low, narrow deltaic plain of the Pasig River, which flows northwestward to Manila Bay. The swampy delta of the southward-flowing Pampanga River lies to the north of the city. Immediately to the northeast and east of the urban region lies a stretch of lowlands, beyond which rise the peaks of the southern range of the Sierra Madre. Laguna de Bay, the large lake from which the Pasig River flows, flanks Metropolitan Manila to the southeast. Enclosing Manila Bay to the west is the mountainous Bataan Peninsula. Although the city’s area is constricted, it is an excellent port site because of its sheltered harbour, its access to inland agricultural areas by way of the river, and its relative proximity to the Asian mainland.
