In the KOHLosseum, located in the former sauerkraut factory in Wesselburen, visitors will learn much of interest and of the history of cabbage growing and the processing of the vegetable. The method of processing Dithmarschen cabbage to sauerkraut is presented in the sauerkraut workshop. Historical implements, tools and farming machinery are on display in the adjoining cabbage museum.
Until 1995, over 120 staff were at work in the sauerkraut-canning factory Philipp & Co. Wesselburen, founded in 1948 by the Philipp family. Hubert Nickels, formerly Production and Operations Manager in the company Philipp & Co. Wesselburen, decided together with Martin Kehl and Achim Krumbiegel to set up the KOHLosseum. In 2002, the support association Förderverein KOHLosseum e.V. was formed, which integrated the sauerkraut workshop, a farmers' market and a cabbage museum under one roof.
