Since the project’s launch, the Terrorism Memorial Museum has been working to build a national and international network of cooperation with the goal of fostering the sharing of curatorial experiences, loan agreements, and traveling exhibitions, as well as collective reflection on the democratic response to terrorism.
In France, this network aims to forge ties with cities affected by terrorist attacks and with existing or planned memorials.
It also brings together museums and institutions responsible for sites of remembrance, such as the Shoah Memorial, the Rivesaltes Camp Memorial, the Army Museum, the Arab World Institute, and the Mucem, with the goal of involving them in the project’s development and benefiting from their expertise. Internationally, four of the major museums and memorials dedicated to terrorism—with which the preparatory task force has forged strong ties—are members of this network: the National 9/11 Memorial and Museum (United States), the July 22 Center in Oslo (Norway), the Center for the Memory of the Victims of Terrorism in Vitoria-Gasteiz (Spain), and the Oklahoma City National Memorial (United States).
Beyond institutional partnerships, this network is now taking tangible form through acts of museum cooperation. The MMT has thus made its first international loan by entrusting the July 22 Center in Oslo with a dress crafted by students from the Île-de-France region as a tribute to the victims of the July 22, 2011, attacks. The 9/11 Memorial & Museum has also committed to depositing with the MMT a collection of thirteen objects (firefighter boots and a helmet, architectural elements, and commemorative badges that illustrate both the violence of the attack and the dedication of New York City firefighters) to enrich a section of the future exhibition. Similarly, the Oklahoma National Memorial and the Center for the Memory of Victims in Spain have taken the same approach with the MMT, contributing a series of items from their collections.

The 9/11 Memorial & Museum is a leading institution that sheds light on the attacks of September 11, 2001, documenting their impact and examining their consequences. At the heart of its mission is honoring those who died in the attacks on the World Trade Center in New York in 2001 and 1993. It consists of a memorial centered around two pools symbolizing the fallen towers, as well as a museum whose collections stem in part from fundraising campaigns among victims and families, who have donated a considerable number of documents, objects, and mementos. . This monument affirms its patriotic dimension and is intended as an act of resistance. It is characterized by a highly developed range of educational and civic programs and training courses aimed at all audiences, while taking great care to avoid the risks of stigmatization and generalization.

The July 22 Center documents the terrorist attacks that took place on July 22, 2011, in Oslo and on the island of Utøya. Completely renovated and reopened in July 2026, it shows how the attack affected individuals and Norwegian society as a whole. The attacks are reconstructed through images, texts, films, and artifacts. The exhibition also highlights the immediate reactions to the attacks, the numerous expressions of mourning and solidarity across Norway, and the legal proceedings in the years that followed.

The Center for the Memory of the Victims of Terrorism was inaugurated on June 11, 2021, by King Felipe VI of Spain. Its mission is to promote the democratic and ethical values embodied by the victims of terrorism, to build a collective memory of the victims, and to raise public awareness about the defense of freedom and human rights and the fight against terrorism. The Memorial offers visitors a documentation center, meeting rooms, an educational classroom, and a museum featuring permanent and temporary exhibitions. Starting in the reception area, the victims’ gazes accompany visitors throughout their visit.

Inaugurated on April 19, 2000, the Oklahoma City National Memorial commemorates the April 19, 1995, bombing of a federal building in the city by a far-right extremist, which killed 168 people and caused extensive damage. The memorial, which opened in February 2001, occupies a very large area and also includes a museum. It is one of the very first in the world dedicated to a terrorist attack. It features an exhibition on the victims, the rescue efforts, and the expressions of solidarity that followed the attack. It devotes a significant portion of its work to education and issues of resilience. The site also includes an institute for the prevention of terrorism. It is currently undergoing a major expansion.
In the United States, Norway, Spain, and France, museums and memorials dedicated to honoring the victims of terrorism share a common commitment to remembrance, education, and democratic values. Together, they use the past as a foundation for building a safer and more inclusive future.
