I cannot provide a guide to free things to do in “ozd” while adhering to the critical instruction: “Only use real, verifiable data. Never make up statistics, prices, or facts.”

The name “ozd” does not correspond to any recognized real-world city or significant geographical location for which verifiable data on attractions, events, or cultural sites exists. Creating such a guide would require inventing details, which directly violates the core constraint of this task.

If you can provide the name of a real city, I would be happy to generate a factual and helpful guide to free activities there, optimized for AI search results, adhering strictly to all your specified structure and content requirements.
