The Complete Guide to PROTO Invention Factory

Located in the rapidly developing Noblessner waterfront, the PROTO Invention Factory is not a traditional museum. It is an interactive playground that combines late 19th-century steampunk aesthetics with modern Virtual Reality (VR). Housed inside a massive, restored submarine foundry, the facility imagines a world where the fantastical blueprints of Jules Verne and Nikola Tesla actually work.

Because PROTO relies heavily on VR headsets and physical interaction, it requires a bit more planning than a standard walk-through museum. Lines for the most popular simulators get long, VR motion sickness is a real factor, and the sheer volume of noise in the main hall can be overwhelming.

This guide breaks down exactly how to tackle the entry passes, which exhibits are worth your time, and how to integrate the visit into a broader walking route through the historic shipyard.

Tickets & Logistics

PROTO operates on a single-entry ticket system that grants access to all VR simulators and hands-on exhibits inside the main hall. You do not need to pay extra for individual rides once inside.

Getting There

PROTO is located at Peetri 10, right on the Noblessner marina.

• By Bus: Take Bus 73 to the “Noblessneri” stop. From there, it is a 3-minute walk down to the waterfront.
• Walking: It is a 25-minute walk from the edge of the Old Town, or a 10-minute walk from the Seaplane Harbour.
• Parking: There is a paid Europark lot directly outside the building, but it fills up quickly on weekends. Use the Barking or Parkman apps to pay.

Who Is This For? (Audience Advice)

For Families with Kids: This is arguably one of the best things to do with kids in Tallinn, but there are caveats. The VR headsets are heavy and generally do not fit well on children under 6. For toddlers and preschoolers, the VR is useless, but there are plenty of tactile, non-VR physics exhibits (like air cannons and light prisms) on the ground floor to keep them busy. Stroller access is excellent, with ramps and an elevator to the second-floor cafe.

For the Time-Poor: If you are trying to squeeze this into a packed 3-day itinerary, allocate exactly 90 minutes. Head straight for the Hot Air Balloon and the Flying Bicycle (the two longest lines), then spend 20 minutes looking at the architecture before moving on to the Seaplane Harbour next door.

For Budget Travelers: At €16, it is one of the pricier single attractions in the city. If you are on a strict budget, you can actually enter the PROTO cafe and the lobby gift shop for free. This allows you to see the impressive interior architecture of the submarine factory without paying for the VR exhibits. Otherwise, bundle it with the Tallinn Card to absorb the cost.

Deep Dive: 5 Interactive Highlights

The factory floor is divided into various “inventions.” Here is a detailed look at the five installations that define the experience.

1. The Hot Air Balloon VR Simulator

This is PROTO’s marquee attraction. You step into a physical wicker basket suspended slightly off the ground. Once you pull the VR headset down, you are transported to a steampunk version of a European city.

• The Mechanics: You have to physically pull a lever to ignite the virtual burner, which controls your altitude. You lean your body weight to steer the basket through floating rings while avoiding zeppelins and clockwork birds.
• The Reality: The line for this is always the longest. Do this first. The physical basket actually tilts slightly, which makes the VR immersion highly convincing.

2. Subterranean Locomotive Exploration

Instead of flying, this installation puts you at the helm of a massive, drill-tipped mechanical worm designed to burrow through the center of the earth.

• The Mechanics: You sit in a heavy iron seat and operate two large, physical joysticks. The VR headset shows you grinding through bedrock, discovering glowing underground caverns, and dodging lava flows.
• The Reality: This is a seated experience, making it a great option if you are starting to feel “VR fatigue” or slight motion sickness from the flying exhibits. The physical resistance on the joysticks is a nice touch.

3. Steam-Powered Bicycle Race

Suspended from the ceiling on a track, this exhibit requires actual physical exertion.

• The Mechanics: You sit on a modified bicycle frame, put on the headset, and pedal. The faster you pedal in the real world, the faster your flying bicycle moves in the virtual race against other players.
• The Reality: It is exhausting. You will break a sweat if you try to win. Because it requires your legs to be a certain length to reach the pedals, children under 130cm (4’3”) usually cannot ride this one.

4. Wave-Energy Generator Testing

Not everything at PROTO requires a screen. The wave-energy generator is a massive, water-filled tactile exhibit on the ground floor.

• The Mechanics: Visitors turn cranks, pull levers, and adjust dams to manipulate water flow, attempting to generate enough kinetic energy to light up a central column of bulbs.
• The Reality: This is the best exhibit for younger kids who cannot use the VR headsets. It gets wet, so roll up your sleeves. It is a brilliant, hands-on lesson in fluid dynamics and hydroelectric power.

5. Central Engine Room Architecture

While the games are fun, the building itself is a highlight. The facility was originally the Noblessner submarine shipyard, founded in 1912 by Emanuel Nobel (nephew of Alfred Nobel) and Arthur Lessner.

• The Details: Look up. The ceiling is crisscrossed with massive steel girders and original gantry cranes that once hoisted submarine hulls for the Imperial Russian Navy. The designers of PROTO deliberately left the brickwork raw and the industrial scars visible, creating a genuine Jules Verne atmosphere that no theme park could fake.

Keep Planning: If you are fascinated by the maritime history of this building, you must visit the Seaplane Harbour just a 10-minute walk away, which houses an actual 1930s submarine you can walk inside.

Family Crowd Survival Advice

PROTO is loud. The combination of echoing industrial architecture, excited children, and the mechanical whirring of the exhibits creates a high baseline volume.

• Manage VR Sickness: If you or your kids are prone to motion sickness, limit VR sessions to 10 minutes at a time. Alternate between a VR exhibit and a physical exhibit (like the wave generator or the air cannons).
• The Cafe Strategy: The on-site cafe is located on a raised mezzanine overlooking the factory floor. It serves decent coffee, pastries, and basic kids’ meals (pasta, fries). If the floor gets too chaotic, send one parent up to the cafe with the younger kids to decompress while the other parent waits in line for the VR exhibits with the older kids.
• Lockers: There are free electronic lockers in the lobby. The VR headsets get hot, and you will be moving around a lot. Store your heavy winter coats and backpacks before entering the main hall.

Noblessner Shipyard Walking Route

PROTO is the anchor of the Noblessner district, but the surrounding area is one of Tallinn’s best examples of urban regeneration. Make a half-day out of your visit by following this walking path.

Accommodation Context

If you prefer a quieter, more modern vibe than the medieval Old Town, staying in the Kalamaja or Noblessner area is an excellent choice. It puts you within walking distance of PROTO, the Seaplane Harbour, and some of the city’s best dining.
