This paper explores the key role of cooperation of European social projects in practice aimed at improving care for the elderly. Focusing on the implementation of home help projects with elderly housewives and residence services, the paper analyzes how the interrelationship between the implementation of European projects contributes to the achievement of quality care, social inclusion and dignified aging. Through a literature review, analysis of completed projects and exchange of information with relevant stakeholders, the paper explores the best practices and results of home help projects and residence services for the elderly. The realized products of the project, but also aspects of cooperation, are considered as factors in the successful realization of not only the project goals, but also the development and improvement of the community. The paper also investigates how these projects contribute to the promotion of social interaction, mental well-being and provide the opportunity for older people to remain active participants in society. By analyzing the results, the possibilities of further improvement of these initiatives are identified in order to ensure the continuous growth of the quality of care and support for senior citizens. Through this work, a contribution is found to the understanding of the key aspects of the importance of the implementation of co-financed European projects in the care of the elderly and to encouraging the further development of innovative approaches as a basis for further strategies and policies that will support dignified aging and an inclusive society throughout Europe.
