This Handbook sets out and assesses the international legal framework governing the protection of cultural heritage. Cultural heritage is frequently not bounded by national territory and can only effectively be protected through international cooperation. This is a primary driving force of contemporary multilateral, regional, and bilateral initiatives, including legal measures. Accordingly, the Handbook is primarily focused on public international law, but it embraces also aspects of private international law and comparative law. It analyses the substance of cultural heritage protection and explores its links with other areas of public and private international law, as well as the ways in which cultural heritage law is contributing to the development of international law itself.
