The Pasig River Light was the first light station in the Philippines when it was established in 1642. The first lighthouse tower in the country was erected in the station and first lit in 1846. It was then located on the north jetty at the mouth of Pasig River in San Nicolas, Manila, marking the entrance of the river for vessels cruising Manila Bay, looking to dock on the inland Port of Manila that was then located along the banks of the Pasig River in Binondo and Intramuros.
