Architectural Metalwork

Marble Arch, St Paul's Cathedral, Palace of Westminster, or the V&A, if you have walked around London for 10 minutes

Case Study: Marble Arch

Originally constructed as an extension to Buckingham Palace, the Marble Arch was relocated to its present site in 1851. Since its conception, the structure has presented persistent challenges in terms of urban design and, at one stage, functioned as a police station. Now serving primarily as a ceremonial gateway, the Arch had fallen into a state of deterioration; however, the lanterns and gates have recently been restored and returned to full working order.

Arts Heritage was required to reconstruct a substantial number of missing or damaged components using traditional craft techniques. As part of this programme of architectural metalwork restoration, a previous survey had incorrectly identified the side gates as iron and consequently specified them for painting. Our investigation, however, revealed intricate bronze heraldic details and acanthus motifs throughout the scheme. This discovery enabled us to reverse the earlier restoration interventions and to re-patinate the bronze using original foundry methods, employing direct heat and stippling—techniques that continue to be used in contemporary fine-art foundries.

Metalwork Restoration & Conservation | Arts Heritage

Historic metalwork is an essential feature of many heritage buildings and public spaces, from wrought iron railings and gates to bronze lanterns, brass detailing, and architectural features. Over time, exposure to the elements, pollution, and general wear can lead to deterioration, requiring careful restoration and conservation to preserve both function and aesthetic integrity. At Arts Heritage, we have worked on some of the UK’s most significant metalwork restoration projects, including St Paul’s Cathedral, the Palace of Westminster, the British Library, the British Museum, the Crown Estate, and the Victoria & Albert Museum. Our expertise covers a wide range of ferrous and non-ferrous metals, with a focus on both structural repair and faithful conservation.

Our Approach to Metalwork Restoration

Every project presents unique challenges, from ironwork corrosion and structural weaknesses to bronze and brass oxidation. Our approach combines traditional blacksmithing and metalworking techniques with modern conservation methods to restore pieces while maintaining their historical authenticity.

• Iron & Steel Conservation – Stabilisation and repair of wrought iron railings, gates, and decorative ironwork, preserving original craftsmanship where possible

• Bronze & Brass Restoration – Cleaning, patination, and conservation of historic lanterns, statues, and architectural bronze features

• Structural & Surface Repairs – Addressing fractures, missing components, and surface deterioration while ensuring stability and longevity

• Protective Treatments – Application of specialist coatings and treatments to prevent corrosion and prolong the life of the metalwork

Preserving Metalwork Heritage

From the grand iron railings of historic estates to ornate metalwork on public monuments and buildings, these features are integral to Britain’s architectural heritage. The aim of restoration is not just to repair but to preserve the character and craftsmanship of each piece, ensuring it remains part of the landscape for years to come. For those responsible for historic metalwork, cast iron features, or architectural bronze, we are always available to discuss restoration needs or provide expert guidance on conservation.
