Freestanding stone sculptures are timeless works of art that require careful attention to maintain their stability and longevity. To ensure their preservation, follow these best practices:

1. Material Selection: Choose durable stone types like granite or marble, which resist weathering and erosion. Avoid porous stones in humid climates.

2. Base and Foundation: A solid, level foundation is critical. Use reinforced concrete or stable ground to prevent tilting or sinking over time.

3. Environmental Protection: Shield sculptures from extreme weather by applying protective sealants or placing them under sheltered areas. Regularly clean surfaces to prevent moss or lichen growth.

4. Structural Integrity: Ensure proper weight distribution and avoid overhanging designs that may weaken over time. Use internal supports if necessary.

5. Regular Inspections: Check for cracks, chips, or erosion annually. Address minor damages promptly to prevent further deterioration.

By adhering to these practices, artists and conservators can ensure that freestanding stone sculptures remain stable and visually stunning for generations.
