The Diocesan shrine and Parish of Our Lady of Light (Nuestra Señora de la Luz) is one of Cainta's oldest churches. Built in stone in 1707 (Jesuit effort) and completed under Father Joaquín Sánchez in 1716. 

It was elevated to a parish in 1760.

The church has valuable Spanish-era art, old paintings, murals (including one by National Artist Fernando Amorsolo), etc.

The Cainta Heritage Monument is a prominent landmark and symbolic monument that represents the town’s identity and cultural pride.

It stands in the middle of a major junction — often used as a directional or meeting point by locals and travelers.
