Pinagrealan Cave (‘Kuweba ng Pinagrealan’), once also called Minuyan Cave, is located in Barangay Bigte, Norzagaray, Bulacan. It is situated at the foot of the Sierra Madre Mountains, near to the famous Ipo Dam.

It is one of the most important caves in our country. It is part of a series of caves in the same location. At least two of the other caves have been destroyed by the quarrying company.

We must protect Pinagrealan Cave and the surrounding karst landscape. It is our heritage.

 

In 1896 Andrés Bonifacio (‘the Father of the Philippine Revolution’) and the Katipunero Revolutionaries used Pinagrealan Cave as a hide-out from the Spanish. Andrés Bonifacio was the Supreme President (‘Kataastaasang Pangulo’) of the Katipunan secret society at the time.

From 1899 to 1901 General Emilio Aguinaldo used Pinagrealan Cave as a safe-haven during the Filipino-American war.

Between February 1945 and August 1945 the Imperial Japanese Army used Pinagrealan Cave as a hide-out. It is thought that they stored gold and precious items in or near the cave.

Not only is Pinagrealan Cave a historical site of significance, it is home to threatened wildlife—including bats, birds, snakes, frogs, and other reptiles—as well as fish and water-dwelling species.

Wildlife regularly visit the caves as they transit across the Sierra Madre Mountains looking for food and shelter. Sightings of the Philippine Eagle have been made here.

According to the Department of Environment and Natural Resources “caves are a valuable natural resource for their scientific, historical and cultural value.”
