This work seeks to provide legal tools for the protection of the Ecclesial Cultural Heritage, with the aim of maintaining the purpose for which they were created, and rescuing and preserving their historical value. We start with an analysis of the value of these assets from Sacred Scripture and the history of the Church, arriving at the position of the Second Vatican Council and the Code of Canon Law. Tools are provided from Civil Law, International Law, Colombian Legislation and Canon Law in order to carry out an analysis of the factual situation of national ecclesiastical cultural property owned by the Colombian Catholic Church.
