Mostostal Warszawa completes works at the Pomeranian Dukes’ Castle in Szczecin

The reconstruction of the northern wing, along with the modernization of the terrace and northern slope, has crowned the largest investment in the Szczecin Castle in the past 50 years. The works, carried out since 2022, amounted to nearly PLN 85 million gross.

- The implementation of the project at the Pomeranian Dukes’ Castle is a great source of satisfaction and pride for us. It required not only top-level engineering but also sensitivity to historical heritage. We successfully combined modern technology with respect for tradition and the unique character of this place. I would like to congratulate the entire Construction Team for their professionalism and excellent work, thanks to which Mostostal Warszawa could help restore the splendor of one of the most important cultural landmarks of Pomerania - said Jorge Calabuig Ferre, President of the Management Board of Mostostal Warszawa.

Reconstruction with respect for history

The most challenging and technically demanding part of the investment was the reconstruction of the Castle’s northern wing, which had been destroyed in a building collapse in 2017. The Mostostal Warszawa team, in cooperation with conservation specialists and archaeologists, faithfully recreated the structure according to its historical appearance, including the reconstruction of original vaults that had survived only partially after World War II.

Particular attention was paid to structural and user safety: foundations were reinforced, new waterproofing and fire protection systems were installed, and all internal installations were replaced. All works were carried out in close cooperation with the Provincial Heritage Protection Office in Szczecin.

New life for the northern terrace and slope

In parallel with the reconstruction of the wing, the modernization of the northern terrace and slope was completed, along with the securing of the tunnels located beneath them. Following recommendations from experts at the Building Research Institute, the slope was reshaped and reinforced with a new embankment structure. Its surface was planted with over 20,000 stabilizing and turf-forming plants that strengthen the ground and enhance the landscape qualities of the area.

The greenery was designed to reflect the historical layout of the former castle moat, as shown on 17th-century maps of Szczecin. Bugleweed, cranesbills, and cherry laurels create a composition inspired by the color of water, while a row of columnar hornbeams marks the former moat line and accentuates the Castle’s monumental form.

The northern terrace—similarly to the previously renovated southern and eastern terraces—now features a new surface, stylized small architectural elements, flower beds and planters, as well as seating areas. Accessibility improvements were also introduced to ensure convenient and safe visiting for people with disabilities.

Engineering precision and conservation sensitivity

Due to complex geotechnical conditions and the historical nature of the building, the project posed a significant engineering challenge. Mostostal Warszawa implemented solutions that ensure the stability of the entire castle hill, including the strengthening and securing of underground corridors with a total length of over 270 meters. All works were carried out with full respect for the historic fabric and conservation requirements.

The Castle restored to its full glory

The completion of the project marks the restoration of the Pomeranian Dukes’ Castle to its original architectural form and full functionality. The renewed spaces, new amenities, and carefully recreated historical details ensure that the Szczecin Castle remains one of the most important and beautiful monuments of Western Pomerania.

The project titled “Comprehensive development of terraces and reconstruction of the northern wing of the Pomeranian Dukes’ Castle in Szczecin” was implemented as part of the Regional Operational Programme of the West Pomeranian Voivodeship 2014–2020, co-financed by the European Union and the budget of the West Pomeranian Voivodeship.
