Alter Markt
The square has an eclectic assembly of buildings, most of them postwar. However, two 16th-century houses survived the war intact—Nos. 20 and 22, which are today a Kölsch brewpub, Zum Prinzen. The oldest structure dates from 1135. In late November and December, Alter Markt is the site of one of the city's prettiest Christmas markets.
