The people of Cologne take great pride in the Dom, and there is no doubt that it forms a part of their psyche. Work on the great Gothic cathedral first started in 1248, and it was not fully completed until 1880. The relics of the Three Kings, or Magi, are on display in the cathedral, as are the cathedral’s art and treasure collection. It's possible to climb the lofty spires of the Cathedral (€4/2), one of which stands at 157 meters in height. There are guided tours in English twice daily (once Sunday) at 10:30 and 14:30.
