Friend Association of the Castro de Viladonga was created in February, 1989, when the Museum had been open to the public for two years; it was promoted by a group of people linked to culture and cultural heritage work in Lugo and Galicia. It was constituted then by 25 founding partners.
The Association develops a very positive work for the Museum and the Hillfort, both in its promotion and diffusion as in the support of all kind of activities, among them collaboration in the celebrations associated to the International Day and the Night of Museums or making replicas of pieces from the Hillfort and other cultural products that serve as a promotion of this patrimonial set. Key milestones of the Association were, in 1991, the launch of Boletín CROA and a complete website launched in 1997, and renovated in 2008.
About two hundred partners support the Association today and back its permanent collaboration work with the Museum and, by extension, the care and divulgation of cultural heritage.
