Online regional portal Chamber offers access to digitized local history content. The portal is co-created by Slovenian public libraries with partner institutions (museums, archives, other organizations and private individuals). The portal is managed by the Central Library of Celje.

On the portal Chamber is on display special Album Celje, which brings valuable insight into the city's history through photographs of people, streets, buildings and everyday moments. It is part of a nationwide project Slovenia Album, which collects, preserves and shares the photographic heritage of our places. The Celje Album brings together memories that testify to life in the city in the past, and allows Celje's rich past to come to life in modern times.

Instead of a house – a museum – we built virtual home on the World Wide Web, always unlocked and accessible from any point on the globe.
