The Derry Walls are a significant historical monument, standing as one of the finest examples of a walled city in Europe. Any work carried out on such a site requires a deeply respectful approach and a high level of technical proficiency. We recently completed a heritage metalwork reproduction project to design, manufacture, and install bespoke railings for a stone plinth located directly on the walls.
The brief for this project was specific and demanding. We needed to create a safe, functional barrier for public safety, but it was vital that the final result looked like it had always been there. This requires a unique blend of traditional craftsmanship and modern engineering.
The Importance of Heritage Metalwork Reproduction
It is incredibly easy to get modern metalwork wrong on an ancient site. If the design is too contemporary or the finish is too “perfect,” it stands out for the wrong reasons, detracting from the historical narrative of the stonework. This is where professional heritage metalwork reproduction becomes essential.
For this project, our team conducted a visual audit of the surviving historical railings in the vicinity. We looked at the original blacksmithing techniques used in the area to ensure our new ironwork would replicate that original style perfectly. By matching the visual weight, the taper of the bars, and the specific spacing of the vertical pickets to the historical context, we ensured that the new addition respects the heritage of the monument.
Built to Last: Materials and Engineering
While the design is traditional, the materials we choose for heritage metalwork reproduction are modern to ensure longevity. We used high-quality structural steel to ensure the railings are not only aesthetically pleasing but also safe and durable for a high-traffic public area.
On a historic site like the Derry Walls, maintenance can be difficult. Therefore, we applied a rigorous two-stage finish to protect the metal from the harsh Northern Irish weather:
- Galvanising: We used a hot-dip galvanising process, submerging the steel in molten zinc. This creates a metallurgical bond that provides a permanent, rust-proof barrier, even if the surface is scratched.
- Powder Coating: We applied a durable, architectural-grade powder coat over the galvanised layer. This gives the railings the correct period finish—typically a satin or matte black—while providing an extra layer of defense against the elements.
Precision Installation on Historic Stone
Installing new metalwork into ancient masonry is a delicate task. Our team had to ensure that the fixings used were secure enough to meet modern safety standards without damaging the integrity of the historical plinth. This involved precision drilling and the use of specialized resins that protect the stone from cracking or moisture ingress over time. Every anchor point was carefully placed to ensure maximum stability with minimum impact on the original stone.
The Result: A Seamless Addition
The new railings now sit comfortably on the plinth, looking integrated and natural. They provide the necessary safety for visitors walking the walls without distracting from the magnificent stonework of the monument itself. The project demonstrates that safety requirements do not have to compromise the visual history of a landmark.
At Metal Made Special, we believe that heritage metalwork reproduction is about more than just copying old designs; it’s about preserving the character of a site for future generations while using the best modern methods available. This project is a perfect example of how we combine traditional aesthetics with 21st-century engineering to deliver results that are built to last.
