Bastion Colomb, Military fortification in Poznań, Poland
The bastion contains a three-story blockhouse within Marcinkowski Park and features remaining wall sections along Aleja Niepodległości street in central Poznań.
Constructed around 1854 as part of the polygonal Poznań Fortress system, the bastion was designed by architect Karl von Grolman during the Prussian control period.
The structure stands as a testament to nineteenth-century military architecture and earned recognition on the Polish cultural heritage register in January 1985.
The lower section of the blockhouse now functions as a pub, while the tunnel at the lowest level serves as a retention basin for groundwater management.
The bastion's earthen rampart remains intact despite modifications during World War II and the intersection created by Powstańców Wielkopolskich Street.
