The Centre for International Light Art (CILA) is an art museum in Unna, Germany. It is the world’s only museum that is exclusively dedicated to the collection and presentation of light art.

The CILA is located at the heart of the city of Unna, in the former Linden brewery, a red brick industrial building complex dating from the 19th century. Its landmark is an installation of Fibonacci numbers by Italian artist Mario Merz. The light art installations are integrated into the industrial structures of the brewery’s former cellar vaults.

Established in 2002, the museum’s permanent exhibition shows works by twelve internationally renowned light artists: James Turrell, Keith Sonnier, Mario Merz, Joseph Kosuth, Mischa Kuball, Rebecca Horn, Christina Kubisch, Jan van Munster, François Morellet, Christian Boltanski, Brigitte Kowanz and Olafur Eliasson.

In addition to the permanent and temporary exhibitions, the center organizes conferences, symposia and workshops, and serves as a forum for discussions. The CILA is a major part of the regional cultural project Hellweg – Ein Lichtweg (Hellweg – A Way of Light), which links light art projects along the historical Westphalian Hellweg travel route. Within a distance of only a few miles around the CILA, works by Rosemarie Trockel, Kazuo Katase, Michael Batz, Claudia Wissmann, and Jan Philip Scheibe are shown.
