Långe Jan (Long Jan) is a 41-meter-high lighthouse built on the island of Öland, it is the highest facility of this type in the whole of Sweden. It was entered in the register of monuments.
The lighthouse was built in 1785, initially it was 36 meters high and 12 meters in diameter. Currently, an ornithological station is located next to the lighthouse. Visibility from the top of the lighthouse is 26 nautical miles.
The name of the lighthouse comes from a medieval chapel that once stood nearby. After the Reformation, the chapel in the Swedish church was demolished, and the rubble was used to build the lighthouse. Today, a symbolic cross stands on the site of the former chapel.
Originally, it was lit with an open flame, and the coal was stored in specially designated rooms. Only in the mid-nineteenth century, a more modern lamp was installed.
