The Eger minaret (Hungarian: Egri minaret or Kethüda-minaret) is an Ottoman era minaret tower located in Eger city, northern Hungary. It is the most northern minaret left from Ottoman rule in Europe. The minaret is 40 metres (131 feet) high and built from red sandstone. It was built in the early 17th century as part of the Djami of Kethuda mosque and used for the Muslim call to prayer (Adhan). The mosque no longer exists, but the minaret survives as a preserved monument of Hungary and a major tourist attraction of Eger. There are 98 steps on the spiral staircase inside, which leads to a balcony at 26 meters from the ground offering unique views of the surrounding city.
