Odd cemeteries in the Philippines

Metro Manila (CNN Philippines) — This November, we commemorate the deaths of those we love. How we remember them varies from one culture to another.

These strange cemeteries in the Philippines are testament to that.

The Hanging Coffins of Sagada are suspended using ropes and wires from limestone cliffs in Echo Valley in the Mountain Province.

The Igorot people of the Cordillera region have practiced this "burial in the sky" for nearly 2,000 years. The site is within the vicinity of Lumiang Burial Cave, where more coffins are stacked at the cave's entrance.

They believe that hanging the coffins from the cliffs brings the dead closer to their ancestors.

The ritual is reserved for those who died of old age or natural causes. The coffins of elders and those with important positions in the tribe are placed higher on the cliffs.

The Underground Cemetery of Nagcarlan, Laguna was built in 1845 by Franciscan Fr. Vincente Velloc. The site is located beneath a church, with the oldest tomb dating back to 1886.

The crypt was a meeting place of Filipino revolutionaries, and it also served as a safehouse for Filipino guerrillas in World War II.

It was declared a national historical landmark in 1978.

The Pet Valley Park and Crematory in Silang, Cavite is owned by veterinarian Manuel Reyes.

The park offers burial and cremation services for pets, and can save memorabilia from your pets such as fur samples or paw prints on hardened clay.

There are 11 cemetery plots, each named after pet traits like "hyper," "affectionate," or "loyal." 

Pet Valley has catered to dogs, cats, turtles, a goldfish, and a hedgehog.

The Sunken Cemetery of Camiguin went underwater after the third volcanic eruption of Mt. Vulcan in 1871.

The cemetery was still visible during low tide. When the volcano erupted for the fourth time in 1948, the area sunk another 20 feet.

In 1982, an iconic white cross was built on the solidified lava to mark the site and commemorate the dead. It has since become a tourist spot and diving site.

The Cemetery of Negativism, also called the Lost Cemetery, is found in Camp John Hay, Baguio.

Established in the early 1980s by then-commanding general John Hightower, it is located in the camp's Historic Core, along with the Bell House and Ampitheater.

It has since become a symbolic site for burying negative thoughts.

The park has several quirky tombstones with humorous puns. One reads, "Kantdu Nuthin Wright - Born: Dec. 5, 1905, Died: June 14, 1903."

The welcome tombstone, a white slab with the head of a bearded man, says that the cemetery is a "stern reminder" to be positive, and treat the day "like it's your last, though it's the first day of the rest."
