This Handbook provides a cutting edge study of the fast developing field of international law on the protection of cultural heritage by taking stock of the recent developments and of the core concepts and current challenges. The legal protection of cultural heritage has come under renewed focus from the international community and states since the 1990s. This is evidenced by the adoption of a range of international instruments. Countries are also enacting cultural heritage legislation or overhauling existing laws within their own national territory. Contributions address the protection of immovable and movable, tangible and intangible cultural heritage in peacetime and in the event of armed conflict as well as the interaction between specific regimes of cultural heritage protection with other fields of international law, including international criminal law, human rights and humanitarian law, environmental law, international trade, investments, and intellectual property. The last part of the Handbook covers diverse regional systems of heritage protection.
