PROTO invention factory is located in the historic Noblessner Port, originally a submarine factory set up in 1912 by oil baron Emanuel Nobel (of the famed Nobel family) and businessman Arthur Lessner. The newly-decommissioned facilities have now been transformed into one of Tallinn’s most rapidly-developing commercial and leisure areas, and are particularly popular among organisers looking for an edgy, off-beat venue close to the city centre.


One of Noblessner’s largest and most prominent industrial buildings is the foundry – the historical shipbuilding workshop and non-ferrous metal foundry of the Noblessner shipyard. The building was renovated in 2019 and today, it has become an event centre with spacious rooms and modern technical facilities. The building has an educational family centre PROTO invention factory, which is also suitable for holding various events, with additional 266 m2 Pantera Conference Hall and 3 break-out rooms.


PROTO invention factory can accommodate up to 600 guests for receptions, 150 guests for gala – perfect for anyone in search of an unforgettable, steam-punk ambience. Pantera Hall can accommodate 220 people for theatre style and 150 people for gala, 3 break out rooms (16 up to 30 people). Catering for up to 200 is provided by the on-site PROTO Café.

The PROTO Invention Factory’s contribution to environmental sustainability was recognised with the Green Key label this autumn. PROTO has implemented several measures to become fully environmentally friendly, including reducing waste, increasing energy efficiency and introducing eco-friendly products. Estonian products are always preferred in the PROTO Invention Factory. Their exhibits are locally sourced to make the journey from idea to execution short and resource-efficient. A simple principle applies to PROTO catering; the food in the café and at events is largely locally produced, varied, organic and healthy. The menu has delicious options for vegetarians too! In addition, the PROTO Invention Factory has taken a hard stance against chemical cleaning products as well as air pollutants, fertilisers and pesticides.

The PROTO environmental programme seeks to educate, raise awareness of environmental issues and inspire through example.
