Callao Cave

The Callao Cave is the premier attraction in the Peñablanca, northeast of Tuguegarao City, the capital of Cagayan province, Philippines. It's also home 67,000 years ago to the early humans called Tabon Man.

The cathedral-like room Inside the Callao Cave has been turned into a chapel by the local people. A rock formation serves as the altar of the chapel lit by God's rays coming from a rooftop opening.
