We recently received an email submission at Unseen Frequencies from researcher Sebastian Melgaço Martel regarding a long-running investigation in Brazil.

According to his message, the case relates to a supposed pirate treasure connected to the ship Trinidad. The claim is that the treasure may have been hidden on Ilhabela island and encoded within the island’s geography using what he calls “Mystical Geometry”.

The original theory reportedly came from a Belgian engineer living in Brazil in the late 1940s, who spent around 30 years mapping the island's topography and attempting to decode the system.

Sebastian states he has continued investigating the case for the past 15 years and has documented manuscripts, field expeditions, and witness testimony. He also mentions an unusual metallic object recovered from the island which the engineer referred to as “the Chakana”.

We have not yet reviewed the full research material, but we thought it would be interesting to share with the community here in the Veil Seekers Society for discussion.

If anyone has knowledge relating to:

• Ilhabela island history  
• Pirate treasure lore linked to the ship Trinidad  
• Sacred geometry used in landscape mapping  
• The symbolism of the Chakana  

feel free to share your thoughts.

As always, Unseen Frequencies approaches all claims critically and objectively. This thread is simply an open discussion for research purposes.
