Meganebashi or Spectacles Bridge, over the Nakashima River was built in Nagasaki in 1634 by the Chinese monk Mokusunyoujo who was in the second generation of Chinese monks living at Kofukuji Temple. It is said to be the oldest stone arch bridge in Japan along with Edo's Nihonbashi bridge and Iwakuni's Kintaikyou bridge and has been designated as an Important Cultural Property. Megane Bridge is also part of the first group of bridges built over Nakashima river. Megane Bridge is made of stone and is a double arch bridge. It received the nickname "Spectacles Bridge" because its two arches and their reflection in the water create the image of a pair of spectacles. Vehicles are prohibited from crossing the bridge and is strictly prohibited to pedestrians only.
On July 23, 1982, a disastrous deluge washed away six of the ten stone bridges over the Nakashima River.
