If a map or photograph does not load
Check your internet connection and try opening the city again. The List view lets you browse loaded places when the basemap is unavailable. Maps and photographs need an internet connection.
Visiting a place
A map pin identifies a place to explore; it does not establish public access or opening hours. Follow current access rules and signs. Former-site pins may be approximate; their record notes explain the location.
