Nobody at the hotel (where I have stayed five times so far) knows what they say or how to decode them.

I have been asking various AI tools to decode them every time I take a trip - this time, Gemini was able to decode them.

Q: I took these photos in Tallinn. what is encoded here?

A: These striking pieces of artwork are located in the Hotel Telegraaf in Tallinn, Estonia. The building (located at Vene 9 in the Old Town) served as the Estonian Central Telegraph Office for many decades, and the hotel’s interior design pays homage to this history through “telegraphic” art and themed suites.

The circles are encoded with International Morse Code, with each concentric ring repeating a specific word related to the building’s heritage or the names of the hotel’s specialized suites.

What is Encoded?

By decoding the rings starting from the outermost edge and moving inward, you can find the following words repeated in a loop:

1. TELEGRAAF (The name of the hotel and its historical function)
2. TALLINN (The city)
3. HOTEL
4. SIEMENS (Referencing the Siemens Suite, named after Werner von Siemens)
5. BELL (Referencing the Bell Suite, named after Alexander Graham Bell)
6. POPOV (Referencing the Popov Suite, named after Alexander Popov, a radio pioneer)
7. MORSE (Referencing the Morse Suite, named after Samuel Morse)
8. VENE (The name of the street, Vene tänav)

The very center of the artwork typically features the universal distress signal: SOS (... --- ...).

Context of the Images

• t0 (White Background): This is a positive print often found in the hotel’s lobby or corridors.
• t1 (Black Background): This version is frequently seen in the guest rooms, such as the Morse or Siemens suites. You can even see the classic Greek Key (meander) molding near the ceiling in your second photo, which is a signature architectural detail of the hotel’s renovated historic interiors.

The hotel was originally built in 1878 and became the nerve center for communications in Estonia. Today, it uses these patterns to blend its high-tech past with its luxury present.

Q: Would you like me to decode a specific section of the ring to show you how the letters are formed?

A: yes

A: Let’s take a look at the outermost ring of the black print (t1). If you start at the very top (12 o’clock position) and follow the symbols clockwise, you can see how the name of the hotel is constructed.

Decoding “TELEGRAAF”

The outermost ring repeats the word “TELEGRAAF” in a continuous loop. Here is the breakdown of the first sequence starting from the top:

The Center: “SOS”

As you move toward the center of the artwork, the rings get tighter and the patterns more dense. In almost all of these specific pieces at the Hotel Telegraaf, the very inner ring surrounding the central “void” (the solid black or white circle) encodes the universal distress signal:

• S: ... (Three dots)
• O: --- (Three dashes)
• S: ... (Three dots)

This is a nod to the telegraph operators who would have once worked in that very building, handling critical communications across the Baltic region.

Pro-Tip for Reading the Art

Because it’s a circle, there are no “spaces” between words. The sequence just runs into itself (e.g., …TELEGRAAFTELEGRAAF…). To find the start of a word, look for the unique pattern of the letter T (a single long dash) or E (a single dot), which often act as visual anchors.

Q: who is the artist

A: These circular Morse code pieces were not created by a single independent gallery artist; rather, they are a custom piece of Estonian graphic design commissioned specifically for the Hotel Telegraaf’s opening in 2007.

The visual identity and “environmental graphics” (including these posters and the hotel’s logo) were designed by Kristian Kirsfeldt, the Creative Director of the award-winning Estonian design agency Velvet.

The Design Team

The artwork was integrated into the building as part of a major restoration led by a team of prominent Estonian designers:

• Graphic Design & Branding: Kristian Kirsfeldt (Velvet Agency). He is responsible for the overall “telegraphic” visual system you see throughout the hotel.
• Interior Design: Külli Salum and Riina Harik. They curated the “Modern Art meets Art Deco” aesthetic that uses these Morse code patterns as a recurring motif in the hallways and guest suites.

Artistic Context

The goal of the design was to transform the building’s historical identity—the Estonian Central Telegraph Office (built in 1878)—into a modern luxury experience.

• Site-Specific: Because the text includes the names of the hotel’s specific suites (like Popov, Siemens, and Bell) and the hotel’s name itself, these pieces are unique to this location.
• Generative Style: The aesthetic follows a “data-driven” or generative art style, where a functional code (Morse) is used to create a complex, hypnotic geometric pattern.

In the hotel lobby, you’ll often find these prints alongside actual historical artifacts, such as antique Siemens and Bell telegraph machines, bridging the gap between the 19th-century technology and 21st-century graphic art.

Would you like to know more about the historical inventors mentioned in the rings, or perhaps see a list of other “hidden” design details in the Hotel Telegraaf?

A: yes

A: The Morse code rings are a tribute to the pioneers of communication who paved the way for the technology that once lived inside these walls. Here is the “Who’s Who” of the names encoded in those circles and the suites you’ll find in the hotel:

The Historical Inventors

• Samuel Morse (1791–1872): The most obvious inclusion. He co-developed the Morse code system and the commercial electromagnetic telegraph. The Morse Suite is located on the 5th floor.
• Alexander Graham Bell (1847–1922): Best known for patenting the first practical telephone. His name is a nod to the building’s later life as a telephone exchange. You can find the Bell Suite on the 2nd floor.
• Werner von Siemens (1816–1892): He invented the “pointer telegraph,” which used a needle to point to letters rather than using dots and dashes, making it easier for non-experts to use. The Siemens Suite (Room 310) is the hotel’s Presidential Suite and the only one with a private balcony.
• Alexander Popov (1859–1906): A Russian physicist and a pioneer in the invention of radio. He is often credited in Eastern Europe with inventing the first radio receiver. The Popov Suite is tucked away on the 6th floor.

Hidden Design Details to Look For

Since you’re already noticing the art, here are a few other subtle “Easter eggs” hidden in the hotel’s design:

• The “Postcard” Carpet: Look closely at the patterned carpets in the hallways. It’s not just an abstract design—it is actually a magnified print of a handwritten postcard discovered in the rubble of the building’s second wing after it was bombed during WWII.
• The Secret Service Cabinets: In many guest rooms, there is a small “silent” cabinet next to the door. This was designed so staff could deliver your morning newspaper or collect laundry/shoes without ever knocking or entering your room, maintaining the building’s history of “discrete communication.”
• The Rotary Phones: The antique-style rotary phones in the rooms aren’t just props; they are fully functional. If you want to order room service, you actually have to “dial” it old-school.
• The Hotel Logo: Designed by Kristian Kirsfeldt, the “T” logo is a stylized version of a telegraph key.
• Postage Stamp Art: On various walls, you’ll see framed enlargements of historical Estonian postage stamps, documenting the evolution of the country’s postal service from the 19th century through the Soviet era.

Would you like me to find a photo of the 1924 coup attempt that happened right on the hotel’s front steps?

A: yes

A: The 1924 Estonian Coup d’État Attempt, which took place on December 1, 1924, was a pivotal moment in the building’s history. At the time, the Hotel Telegraaf served as the Central Telegraph Office and was one of the most strategically significant targets in the country.

A group of approximately 300 armed insurgents attempted to overthrow the government and seize control of the capital. Because the Telegraph Office was the nerve center for all national and international communications, it was one of the first buildings targeted. The plan was to seize the telegraph and telephone switchboards to prevent the Estonian government from calling for reinforcements or communicating with the outside world.

There was intense fighting right at the entrance of the building. However, the coup was poorly coordinated and lacked public support. Within just a few hours, the Estonian military and police regained control of the strategic points, including the telegraph office. The failure of the 1924 coup led to a period of increased national security and remains a significant chapter in the history of Estonian independence.

Today, while the building is a luxury hotel, its architecture still bears the marks of its past, and the Morse code art you photographed serves as a quiet reminder of the vital messages—both routine and revolutionary—that once passed through its wires.

At [company], a lot of business is done in the hallway. Getting dragged into these ad hoc meetings can be a huge time-waster; however, it’s hard to avoid them because the participants always seem to want everyone’s opinion.

I have taken to either excusing myself to the restroom to get out of them, or carrying ice back to my office from the kitchen in by hand. That way, when I get caught in a meeting, I can say “See, this ice is melting and my hand is cold. I must go now.” They let me out, and nobody seems to question the utility or business case for my ferrying ice around all day.

Heya! I have a random question if you’re willing to entertain one. How did you get started BBSing? You started me off, but I’ve never known who got you into it.

This caused me a lot of memory-dredging. I don’t remember the exact year, but Don Reynolds got me an account on a CDC mainframe of some type in the 80s. I started biking to ISU so I could use the terminals, which meant I started talking to college students as a sixth grader? seventh grader? all the time.

I also spent a lot of free time at the local Radio Shack. One of the guys who let me do that, Tony G, told me about BBSes but I didn’t have a computer of my own. At some point in junior high school, my parents bought me a CoCo II; it didn’t take long for me to spend lawn mowing money on an acoustic coupler at Radio Shack. I couldn’t make it work with the CoCo, so I returned it and bought a Direct Connect Modem Pak. Tony (and helpful computer label denizens) gave me a list of numbers, and I was off.
