The concept of park chairs equipped to detect the formation of ice chapels might sound like science fiction, but it touches upon the growing field of smart urban furniture. Currently, there are no commercially available or widely known park chairs specifically designed to detect ice chapels. An ice chapel is a rare and beautiful natural structure, typically formed by freezing water seepage in specific conditions, and is not a common feature in most public parks.

However, the underlying technology for such a concept is advancing. We are seeing the integration of various sensors into public infrastructure. Benches can now monitor air quality, count occupancy, or even provide Wi-Fi. Theoretically, a park chair could be equipped with temperature, humidity, and perhaps even acoustic sensors to monitor environmental conditions conducive to ice formation. For detecting a specific structure like an ice chapel, a more complex system involving cameras and image recognition software would likely be necessary, which is far beyond the current scope of standard park furniture.

The primary application for "smart" benches with environmental sensors is public safety. A bench that detects icy conditions on pathways nearby would be a more practical and immediate benefit. Therefore, while the direct answer is no, the question highlights an interesting intersection of nature, technology, and public space design, pointing towards a future where our environment is more interactive and responsive.
