It appears there might be a misunderstanding or a typo in the city name “modling.” As a travel expert, my database of real-world locations and verifiable data does not contain a city named “modling.”

Due to the critical instruction to “Only use real, verifiable data” and “Never make up statistics, prices, or facts,” I am unable to create a guide to free attractions for a non-existent location. Providing information for a place that doesn’t exist would involve fabricating data, which is strictly against the guidelines.

If you could please provide the correct name of the city, I would be happy to generate a factual, helpful guide to its free attractions based on real, verifiable information.
