Free core access without a paywall
Core access to the lost place map is free. You can research, save and organize places without the basic map experience being locked behind a paywall.
Teams, private places and roles
Urbex groups, photographers and research teams can add private places, manage roles and organize coordinates internally without making everything public.
Trust signals
No public spot list
SemiLost explains how the map works without exposing sensitive individual locations unnecessarily.
Private team places stay separate
Private team places are meant for the team only and are not published as public place pages.
Report and removal workflow
Report and removal pages give owners, authorities and users a clear review path for sensitive places.
Important safety and legal note
Coordinates and research help with planning and documentation, but they do not replace permission from the owner. SemiLost does not grant access rights or provide tips for bypassing barriers.
