The Lieden are a striking row of houses with characteristic arcades (arches) on the north side of the market square. The row of houses was built in the Middle Ages and replaced the merchants' unfortified stalls and booths. The name "Lieden" is also derived from these "stores". Initially, sales were only made at the windows and the "shutters" were closed at the end of the day. Later, they were extended and sales rooms with counters were built.

The first craftsmen mentioned in the town were bakers and butchers. The row of arcades was partially rebuilt in the 19th century. The right-hand half-timbered side of the Lieden was replaced by new stone buildings in the late classicist style, as the half-timbered houses previously located here with low arcades and wooden beam ceilings had to be demolished due to severe dilapidation. Individual buildings in the left-hand area date back to the 16th century.
