A place worth remembering
Ifugao: forests above the terraces
The terraces are part of a wider agroecosystem. In the DENR framework, upper woodlots (muyung) retain rainwater and nutrients, then release them gradually to the rice fields below.[2]
Palawan: a river connected to its watershed
At Puerto-Princesa, the underground river reaches the sea. UNESCO describes its lower half as brackish and influenced by tides.[3]
Las Piñas: bamboo among the organ pipes
The organ is housed at St. Joseph Parish Church. A Las Piñas City Government account counts 902 bamboo pipes within the instrument’s total of 1,031; the remaining pipes are metal.[4]
Good to know
A few clear answers before you explore.
Are the UNESCO-listed terraces only in Banaue?
No. UNESCO also names the Hungduan and Mayoyao terrace clusters, and Nagacadan in Kiangan; Batad and Bangaan are in Banaue.[1]
What does the park include beyond the underground river?
Its boundary includes the river’s full watershed. UNESCO says this helps protect water quality and quantity.[3]
What happened to the Las Piñas organ in the 1880s?
The city government says a typhoon and an earthquake damaged the church roof, letting rainwater and stones into the organ case and leaving it unplayable for years. Restoration began in 1972 with Johannes Klais Orgelbau; the organ went to Bonn in 1973 and returned in 1975.[4]
