This is an app clip suggestion based on your location. Siri suggestions can suggest things based on many factors such as location, time of day, recent apps, etc. These suggestions can be things like opening an app or texting someone. All of that processing is done on your device. As I said, this is for an App Clip based on your location. An app clip is like a mini app designed to do one single task. For instance, an app clip might be for paying for fuel at a petrol station. App clips are designed to be extremely small so you can download it quickly and easily and the delete them when you’re done. So in summary, you’re seeing a Siri suggestion to download an app clip that is linked to that nearby church. It’s probably some touristy thing. You can change all of your Siri suggestion settings under Settings > Siri & Search
