Heritage & Cultural Industry
Preserving the Kingdom's cultural identity for future generations
Saudi Arabia's heritage is a tapestry woven through millennia—from ancient Nabatean tombs at Hegra and mud‑brick palaces of the Najd region to historic mosques, traditional souks, and vernacular architecture that defines the Kingdom's cultural landscape. Under Vision 2030, the preservation of this rich heritage has become a national priority, with historic sites being restored, rehabilitated, and opened to the world.
At Arabian Company for Protection and Strengthening, we bring a unique combination of conservation philosophy and technical engineering to heritage projects. We understand that historic structures are irreplaceable cultural assets that require the utmost sensitivity. Our approach balances authenticity and innovation—preserving original materials and craftsmanship while discreetly integrating modern strengthening techniques to ensure these treasures stand for centuries to come.
Why Heritage & Cultural Assets Require Specialized Care
Historic structures face a unique set of challenges that demand specialized conservation expertise.
- Authenticity imperative: Interventions must preserve historic fabric and maintain cultural significance.
- Traditional materials: Mud brick, stone, lime mortar, and timber require compatible repair materials.
- Structural instability: Aging foundations, deteriorated walls, and loss of structural integrity.
- Environmental exposure: Decades or centuries of sun, wind, rain, and temperature cycling.
- Previous inappropriate repairs: Cement-based materials that trap moisture and accelerate decay.
- Modern code compliance: Balancing safety requirements with preservation ethics.
- Tourism and accessibility: Adapting for visitors without compromising historic character.
- Documentation gap: Often limited original construction records.
Our Philosophy: Conservation, Not Replacement
True heritage preservation follows a simple but rigorous principle: intervene as much as necessary, but as little as possible. Our approach is guided by international conservation charters and a deep respect for traditional Saudi craftsmanship.
Guiding Principles
- Authenticity first: Retention of original materials and features is always the priority.
- Reversibility: Where modern materials are necessary, they should be removable in the future without harming original fabric.
- Compatibility: Repair materials must be physically and chemically compatible with historic materials.
- Scientific approach: Every intervention is preceded by thorough investigation and documentation.
- Traditional craftsmanship: We employ skilled artisans trained in traditional building techniques.
- Minimal intervention: The least invasive solution that achieves preservation goals is always chosen.
