The project “Light manifestations” is a succession of five European light festivals, each exploring the medium of light and the beauty and benefits that its advancement can bring. The project will be a trans-national, collaborative production between Portugal, Estonia, Latvia, Germany and Slovenia. Each partner organization will have substantial responsibility in the production and development of the project. The light artists from three countries will create site-specific light installations which are inspired by the cultural heritage, art and architecture of the environments of participating cities and countries. The light artists work closely with local artists’ communities and art students targeting educational and interactive aspects. The festivals aspire to reach new audiences and interact with thousands of EU citizens, giving them an active role in cultural experience.

Over the course of the festivals, different seminars, workshops, exhibitions and laboratories serve interested people and professionals with fresh knowledge and ideas.A website will be created to showcase the final artworks done by the artists/designers and public/EU citizens in the public space. The website is an open window to the world (including all EU countries) showcasing art created by thousands of people in EU cities.
