Apple is now publishing public web pages for landmarks and POI in its Apple Maps database: here’s one such place. The website link shows details about the place such as location, name, telephone number and reviews. The design is identical to the cards in the iOS 10 Maps app.
When on an Apple platform, these URLs appear to act as deep links into the native Maps app. If viewing in Chrome or on a non-Apple device like Android, the fallback webpage is loaded. The purpose for these URLs is unclear, but it may possibly foreshadow a larger move by Apple to offer its own online mapping service to compete with Google Maps on the web.
