Following the sudden "lockdown" imposed in march 2020 in order to curb the health crisis linked to the Covid19 pandemic, the MNHA has adapted to the situation by developing educational online content, first on social networks but also on its website. Since then, this content has been systematically referenced on a single platform, the MNHA's Youtube channel entitled "Learning by viewing" (videoguiding of exhibitions, lecture replays, "home made" didactic videos produced by our guides during lockdown, video clips). Find us on Youtube MNHA Learning by viewing.
