Pasig City

Located along the eastern edge of Metro Manila, Pasig borders the province of Rizal and is traversed by the Pasig River, from which it takes its name. Formerly a predominantly rural settlement, the city has developed into a major residential, industrial, and commercial center, particularly following the development of Ortigas Center, which it shares with Mandaluyong and Quezon City. Pasig is also the seat of the Diocese of Pasig, based at Pasig Cathedral, which was established around the time of the town's founding in 1573.

Pasig was formerly part of Rizal province, being transferred to NCR's jurisdiction upon the latter's creation in 1975. Despite this, Pasig continued to serve as Rizal's official capital, and became a city in 1995; Rizal's provincial government later transferred its seat to Antipolo in 2009. Although the capitol had relocated, Pasig remained the de jure provincial capital until 2020, when Republic Act No. 11475 formally designated Antipolo as the capital of Rizal.
