Subterrarium is a self-defined „society to promote and interlink experimental art-forms in Vienna“, which means that they now and then host small-scale acts, performances and exhibitions – all for free. The opening hours are flexible, but mostly limited to Friday evenings. People have to be rather aware of the address to stumble through the unimposing entrance at Jörgerstraße 23 and find themselves in an improvised but cosy basement. With its comfortable second-hand furnishings and self-made fittings, Subterrarium feels like an extended living room, where you – once aware of the location – drop in for an evening beer that you did not really plan on. It just happens the same way as you get stuck in your living room couch, but in this case it includes nice company and enjoyable entertainment.
