About Us


The 2005 World Summit on Social Development identified sustainable development goals, including economic development, social development and environmental protection. The cultural dimension of sustainability is known as “Culture 21”. Since 2005, with the start of United Cities and Local Governments (UCLG) and the first Culture Summit of UCLG in Bilbao culture has been seen as the fourth pillar for Sustainable Development: "The organizing principle for sustainability is sustainable development, which includes the four interconnected domains: ecology, economics, politics and culture". The model is now being used by organizations such as the United Nations Cities Program and Metropolis. Culture 21 is anchored in the Sustainable Development Goals.

Moving towards sustainability is also a social challenge that entails international and national law, urban planning and transport, local and individual lifestyles and ethical consumerism. Ways of living more sustainably can take many forms from reorganizing living conditions (e.g., ecovillages, eco-municipalities and sustainable cities), reappraising economic sectors (green building, sustainable agriculture), or work practices (sustainable architecture), using science to develop new technologies (green technologies, renewable energy and sustainable fusion power), or designing systems in a flexible and reversible manner, and adjusting individual lifestyles so that they conserve natural resources.

Viglas Forum 21 has become the East European Headquarters of the FORO SORIA 21 PARA EL DESAROLLO SOSTENIBLE and World Forum Summit on Sustainable Development. It has been created by the private initiatives of Baron Daniel von Rechitar and Amalio de Marichalar y Saenz de Tejada, Count Ripalda to undertake efforts in all fields of sustainable development by the creation of a Four-Dimensional (4D) Communication Platform for public dialogue between all Stakeholders: municipalities, politicians, businesses, universities, new science technologies.


Our 4D Communication Platform consists of the following Pillars: Cultural, being the basis of the “Viglas Forum 21” creation and bringing together more than 25 years of our efforts in historical projects as “Numancia” and “Viglas Castle Reconstruction”, and also Environmental, Social and Economic - you can see details in the “Pillars” tab. We are planning to organize a specialized conference each quarter on all these mentioned topics.
