It was then located on the north jetty at the mouth of the 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.

[5] From its location at the mouth of the historic Pasig River, which divides Manila into north and south sections, the light was a welcoming beacon for all mariners of inter-island vessels entering the Pasig River and bringing their vessels up for berthing along its busy wharves.

[3] The Spanish colonial lighthouse was demolished in 1992 for unknown reasons, without regard for its historical significance.

The unique feature about this lighthouse was the placement of the first four levels, which were in tangent circles if seen from above (meaning the four circles are sharing one point of their sides or in tangent),[6] except for the gallery-lantern room, which is centered above the fourth level.

The white tower had an effective focal point height of 52 feet (16 m) above sea level and sat at the end of the north jetty at the Pasig River mouth.
