Metal sculptures in public spaces are vulnerable to theft due to their high value and portability. To protect these artworks, a combination of physical, technological, and community-based strategies is essential.

1. Anchoring and Bolting: Secure sculptures to permanent foundations using heavy-duty anchors or epoxy bolts. Underground steel frames can further deter theft by making removal difficult.

2. Surveillance Systems: Install motion-activated cameras or GPS trackers to monitor sculptures. Visible signage warning of surveillance can act as a deterrent.

3. Lighting and Visibility: Place sculptures in well-lit, high-traffic areas where thieves are less likely to act unnoticed.

4. Community Involvement: Engage local residents and businesses to keep watch over public art. Neighborhood watch programs can provide extra security.

5. Tamper-Proof Fasteners: Use specialized bolts or welding techniques that require unique tools for removal, discouraging opportunistic theft.

By implementing these measures, cities and artists can significantly reduce the risk of sculpture theft while preserving cultural assets for public enjoyment.
