Wat Saket

Wat Saket Ratcha Wora Maha Wihan (, usually shortened to Wat Saket is a Buddhist temple ("wat") in Pom Prap Sattru Phai district, Bangkok, Thailand.
The temple dates back to the Ayutthaya era, when it was known as Wat Sakae (วัดสะแก). When Bangkok became the capital, King Rama I (1737–1809) renovated the temple and gave it its present name. Its name roughly translated as "wash hair". Since it was believed that on the way the king returned from the war. He stopped by to take a bath and wash his hair here, before entering inner city.
Phu Khao Thong.
"Phu Khao Thong" (“Golden Mountain”, ) is a steep artificial hill inside the Wat Saket compound.
Rama I's grandson, King Rama III (1788–1851), decided to build a chedi of huge dimensions inside Wat Saket, but the chedi collapsed during construction because the soft soil of Bangkok could not support the weight. Over the next few decades, the abandoned mud-and-brick structure acquired the shape of a natural hill and was overgrown with weeds. The locals called it the "phu khao" (ภูเขา), as if it were a natural feature.
During the reign of King Rama IV, construction began of a small chedi on the hill. It was completed early in the reign of his son, King Rama V (1853–1910). A relic of the Buddha was brought from Sri Lanka and placed in the chedi. The surrounding concrete walls were added in the 1940s to stop the hill from eroding. The modern Wat Saket was built in the early 20th century of Carrara marble.
An annual festival is held at Wat Saket every November, featuring a candlelight procession up Phu Khao Thong to the chedi, along with a long red robe wrapped around the chedi, similar to "Hae Pha Khuen That" (แห่ผ้าขึ้นธาตุ) festival of Wat Phra Mahathat, Nakhon Si Thammarat province in sounthern. Devotees write their names and names of family members on the robe and set the mind to pray, believed to have been fulfilled in prayer. This festival has been carried on since the reign of King Rama V.
At the same period, a great Loi Krathong festival will take place at the temple, along with freak shows such as "Phi Krasue" ("floating female ghost head with glowing viscera dangling below", ), "Khon Song Hua" ("two-headed man", ), "Mia Ngu" ("snake's wife", ), or fun games "Sao Noi Tok Nam" ("little girl falling into water", ) etc. It has been well known among Bangkokians since the past, also at nearby Fort Mahakan community was a hub of the fireworks shop. But after the demolition of the fort and its community, fireworks trading has been banned ever since. 
Phu Khao Thong is now a popular Bangkok tourist attraction and has become a symbol of the city.
Vultures of Wat Saket.
In the early Rattanakosin period (between reigns of Rama I to Rama V) Wat Saket was often used as a place to cremate the dead within the city walls. Since it was located outside the city wall Siamese in those days had a tradition not to cremate the dead within the city walls, because it was believed to cause portentous. The bodies of the dead will be conveyed from the west gate known as the "Pratu Phi" (ประตูผี, "ghost gate", later neighbouring area Samran Rat).
In the year 1820 corresponding to the reign of King Rama II (1809–1824), cholera spread from Penang to Bangkok leading to more than 30,000 deaths in the capital. Wat Saket became the main receiving ground of many dead bodies that were moved in everyday, along with Wat Sangwet in Banglampoo and Wat Choeng Lane in Sampheng. Due to the large number of the deaths, the temple was unable to cremate every dead body, therefore, left some of them in the open area of the monastery where vultures began coming to devour those bodies. The communicable disease kept spreading every dry season in Siam until the early reign of King Rama V, and the temple became the main food court for vultures. Most severe was in 1840 during the reign of King Rama III when one out of ten people in Siam and the surrounding areas were killed by the disease. The last spreading of the disease took place in 1881. At that time as many as hundreds died each day.
These miserable events are in the memory of contemporary Siamese, until it was said that "Raeng Wat Saket" (แร้งวัดสระเกศ, "vultures of Wat Saket"), paired with "Pret Wat Suthat" (เปรตวัดสุทัศน์, "preta of Wat Suthat").
