PROTO Invention Factory


PROTO, which opened its doors autumn 2019, is a vast, Jules Verne-esque lab where revolutionary machines – and the science behind them – are presented through virtual reality and hands-on exhibits. The PROTO Invention Factory combines novel VR technology with technological prototypes more than a century old in an entertaining experiment centre. Though this attraction is primarily aimed at the younger generation, PROTO also offers event and conference halls that are perfect for groups looking for a memorable backdrop.

The PROTO Invention Factory is located in 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. Read more about Noblessner Port on Visit Estonia’s blog post.


PROTO’s largest space, the Nobel Hall, can accommodate up to 800 guests for  receptions, 400 guests for galas and 550 delegates for conferences, while the 220-seat Pantera Hall is better suited to conferences and smaller gatherings. Additionally, the Invention Factory itself can be booked for corporate events – perfect for anyone in search of an unforgettable, steam-punk ambience. Catering for up to 200 is provided by the on-site PROTO Café.
