CDU and CSU Offices Briefly Renamed on Google Maps in Coordinated ‘Eierhaus’ Prank

The stunt highlights how user edits on Google Maps can briefly change official listings.

Overview

  • Reports on Thursday documented dozens of party offices across Germany showing up as variations of “Eierhaus” on Google Maps, with entries spanning Berlin, Hamburg, Bavaria, Hesse and more.
  • The changes used Google’s community-edit tools that let anyone suggest a new name for a place, which automated systems can surface before a manual check catches errors.
  • A Threads user calling themselves “saftsackbeats” posted a note claiming to have submitted many of the edits, though news outlets have not independently verified full responsibility.
  • Google says it is restoring correct information and the CDU told local branches to verify ownership of their profiles so they can lock down listings and reverse future misuse quickly.
  • Several outlets linked the prank to youth protests over a proposed or reinstated military service after police opened a defamation probe into an 18-year-old who carried a viral “Merz, leck Eier” sign in March.
