Heritage, as one of the fundamental concepts of museology, has undergone various definitions and expanded its meaning over time. Broadly speaking, heritage can be defined as everything that surrounds us, that is things and concepts that are deemed significant enough to be preserved and passed on to future generations. For its preservation to be possible, and for heritage to become part of everyday discourse, it is important to increase awareness of its existence and significance. This paper focuses on ways to develop heritage awareness through educational activities in museums and heritage organizations in the city of Zagreb. Educational programs about heritage enable the increase of individual and community knowledge, thus raising awareness of the importance of caring for, valuing, and transmitting cultural heritage. Communicating and interpreting heritage is not limited to museums alone; non-governmental organizations and civil society also participate in spreading awareness of heritage. By advocating for public education and heritage communication, heritage awareness is increasing, and by placing heritage in contemporary discourse through the digitization of promotional and educational materials, we may achieve a form of heritage literacy as one of the steps towards heritage preservation. This paper presents the educational activities of two institutions and two NGOs whose educational endeavours contribute to the development of heritage awareness and preservation.
