The tour kicks off at Mastermind Escape Rooms located at Karori 6, Athina 105 51. Here, you receive your treasure map and tools that set the stage for the adventure. This central meeting point makes it easy to access from various parts of Athens, and the activity concludes back at the same location.
The initial setup involves a brief introduction, after which participants are equipped with everything needed to explore the city on their own. Because this is a self-guided experience, it offers flexibility around timing and pacing, so groups can spend as much or as little time at each stop as they like.

The treasure map guides groups through key sites in the city, including Aiolou street and the Metropolitan Church of Athens. Each stop is designed to be 20 minutes long, providing a manageable pace for both adults and children.
At Aiolou, participants can enjoy a brief visit, discovering local sights and perhaps stopping for a quick photo. The Metropolitan Church offers a chance to appreciate religious architecture and learn about its significance in Athens’ history. The Tower of the Winds adds a touch of ancient engineering, while Hadrian’s Library invites exploration of one of the city’s most notable Roman relics.
These locations not only serve as clues in the treasure hunt but also act as windows into Athens’ multilayered past. The clues challenge participants to observe details like secret spots or architectural features, making the experience both educational and interactive.
The core mystery involves helping a professor locate the Lost Library of Aristotle, one of ancient Greece’s most valuable treasures. The game-style hunt encourages players to solve puzzles and challenges based on historical clues. This element adds an interactive storytelling layer that makes discovering Athens more engaging.
The puzzles are integrated into each site, requiring participants to notice hidden details or solve challenges that reveal new clues. The book of puzzles and tools provided help unlock the locked treasure box, which holds the key to the city’s secrets.
While the 2-hour activity is designed to be comprehensive, groups are encouraged to take their time and enjoy the sights along the way. This flexible approach allows for a relaxed exploration, suitable for families and curious travelers.
