As similar properties come to market — be it former SS headquarters, Nazi hideaways in Bavaria, or estates with ties to collaborators across Europe — the ethical playbook remains unclear. Some argue that transparency should be standard practice: listings should note any significant historical affiliations, especially when tied to regimes of oppression. Others advocate for a more nuanced approach — perhaps including optional documentation, public markers, or partnerships with historical societies. After all, buildings can be repurposed, but history cannot be rewritten.
