At the end of the bridge in Pom Prap Sattru Phai side is an intersection called "Men Pun Intersection", that refers to "cement crematorium intersection". It's an area close to Wat Saket. During the reigns of King Phutthaloetla Naphalai (Rama II) and King Nangklao (Rama III), there was severe epidemics of cholera in Bangkok. There're a lot of dead people and can't be cremated immediately. Many bodies have been left along the road or the temple grounds, so that the vultures are eaten, it's an abomination to those who have seen. The temple that was cremated during that time was Wat Sa Ket, including crematorium made of cement nearby. Presently, the cement crematorium has been demolished but its name still stands today and becomes the official intersection.
