The Bazaars in Halden are a historic building built in 1882, designed by city engineer Gustav Blom Kielland. The building has a characteristic semicircular shape with a front facade facing the town square, and is constructed of plastered brick with iron columns and a slate roof. The Bazaars were built as a replacement for open butchers' stalls, and have had an important function for local butchers and farmers.
The building contained stalls for meat, fish and vegetables, and has been a central part of the town's commercial life. Over the years, the Bazaars have been characterized by historical environmental and hygienic challenges related to the various businesses that have been operated there. Previously, the town's emphasis was on the site, but this is now located in a new building. The Bazaars stand as an important cultural monument in Halden, with its unique architecture and history.
