Submit a Facility Report

All submissions are reviewed by our editorial team. We accept reports of underground facilities, tunnel projects, and military installations not currently in the database.

Before You Submit

  • — We do not accept classified information — ever
  • — We do not publish submissions without editorial review
  • — If accepted, your report will appear as UNVERIFIED until independently corroborated. This is our standard for all public submissions — not a reflection on the submitter
  • — Providing deliberately false information is a misuse of this portal
  • — Your contact information is used only to follow up on your submission — it is never published

The D.U.M.B. Database does not condone or encourage unauthorized access to military or restricted property. Submissions based on illegal entry will be discarded. Do not submit operational details including access routes, patrol schedules, security routines, or internal layouts.
