This article focuses on the idea of ‘human rights city’ and explores its practice. It starts from the concepts of human rights cities and subsidiarity to explain what a human rights city is and delves into the existing literature identifying the challenges to guarantee human rights in local contexts, such as the legal framework, education and training, the institutional structure, and the resources. Our article is based on an empirical-based study of Madrid Human Rights Plan (2017–2019). We carried out semi-structured (...) interviews, focus group, and participant observation to grasp the obstacles that civil servants encounter in the implementation of the Plan. We identify five types of obstacles that we classify as conceptual, ideological, legal, organisational, and budgetary. Our study questions the idea that the local context, just because of its proximity to the citizenry, is the best equipped level of government to guarantee human rights. Without proper training and resources human rights can be lost in translation. Through the identification of such obstacles in a specific case study, we contribute to the academic debate on human rights in practice with the aim of fostering its guarantee in local contexts.
