Preserving historical metal sculptures is a complex task that involves addressing multiple challenges to maintain their artistic and cultural value. One of the most common issues is metal corrosion, which can weaken structures and obscure intricate details over time. Environmental factors such as humidity, pollution, and temperature fluctuations accelerate deterioration, requiring controlled storage or display conditions.

Another challenge is mechanical damage caused by human interaction, vandalism, or improper handling during transportation. Additionally, previous restoration attempts using incompatible materials or techniques can further complicate preservation efforts. Experts must carefully balance conservation with maintaining the sculpture's original appearance, often relying on advanced technologies like 3D scanning and non-invasive cleaning methods.

Finally, limited funding and a shortage of skilled conservators pose significant obstacles to large-scale preservation projects. Addressing these challenges requires interdisciplinary collaboration, ongoing research, and public awareness to ensure these invaluable pieces of history endure for future generations.
