The city was founded by the Romans in the year 50. Before that, it was a Roman castle ("castellum") and a town inhabited by a local German tribe named Ubier at least for 100 years. Archaeologists have found out that the surrounding area was populated already during the stone age.
The most interesting thing to see there is Cologne Cathedral. This church was built from about 1248 to about 1550, but completed only in 1880. The United Nations list it as 'World Cultural Heritage'. Cologne's archbishop Rainald von Dassel brought the relics of the biblical Three Wise Men there in 1164. They are kept in a very beautiful golden shrine in the cathedral. Three golden crowns in the coat of arms of the city symbolize them. They made Cologne a major place of pilgrimage.
Traditionally, the city was always Roman Catholic. That changed only recently after the Second World War,as a result of massive immigration of Protestants from the East of Germany. Still the largest number of people, 41.6%, are Roman Catholic, compared to 17% Protestant. 10% of the people are Muslim.
