Mental health is one of the great challenges for the city of Barcelona. For this reason, the City Council of Barcelona has set it as one of its priorities, by approving the Barcelona Mental Health Plan 2016-2022 in 2016. The day ‘We have put mental health in mind’ is the first meeting promoted by the Barcelona Mental Health Board. It wants to be the space to share projects carried out since the launch of the plan and, in particular, to deepen in one of the topics in which we are focusing efforts from different fields and organizations. Within the framework of the conference, the “Cities with Mental Health in Mind” (International Workshop) will also be held. This conference is a meeting point with other cities that share their commitment to mental health and have the desire to work together to advance with the proposed challenges.
