Süderbrarup is a central municipality in Angeln and belongs to the Schlei villages. In the past, there was a source of radium which was a popular destination for pilgrimages in pre-Christian times. In the meantime, however, this source has been torn down by structural developments.

The Thorsberger Moor is still a popular place of interest, which, as the name suggests, was used as a sacrificial place for the Germanic war god Thor. Many objects of utility and weapons were found, dating back to the 4th century. These findings are so unique that they are now exhibited at the Gottorf Castle in Schleswig.

The historical significance of Süderbrarup is still paramount today. For example, the local railway station is a stopover point for the Angelner Steam Trains, which runs between Süderbrarup and Kappeln and is an experience for both the young and old.

Süderbrarup life is best seen on the last weekend in July, when the Brarup market is open. In the north it is often referred to as "Peermarkt", which is the Low-German word for "horse market". The Brarup market was once a farming market, which has, of course, developed into a colourful amusement mile or, more precisely, the largest annual market in all of Schleswig-Holstein.

History continues to play an active role here, as the horse market still takes place on the market day of each year.
