The Industrial Gas Museum opened its doors to the public in 2013, aiming to promote and protect the old Gas factory of Athens, a monument of industrial heritage that provided energy and lighting in the capital for about 130 years. It is the first industrial museum of the capital, which was added to the museum map of Athens, highlighting one of the few surviving monuments of industrial heritage. The museum visit includes a walk with 13 stops in specific parts of the factory, giving visitors the opportunity to follow the gas production line, marvel at the mechanical equipment and old machines, to discover the role of businessmen and factory workers, to know the working conditions and to familiarize themselves with concepts such as industrial heritage and archeology. The Industrial Gas Museum has a full photographic and archival material, including audiovisual material screenings and interviews of old workers and local residents. It is constantly enriched with objects from the factory itself and interactive applications. Entrance: 2€ Organized guided tour: €4/adult, €2/child (over 6 years old).
