Fridrich Nietzche

Friedrich Nietzsche remains one of the most quoted and least understood philosophers in history. While many know him for the phrase “God is dead,” few realize that he actually lived a quiet, sickly life that ended in madness. For instance, he served as a medical orderly in a war where he witnessed horrors that haunted him forever. Furthermore, his famous mustache was not just a style choice but a massive barrier that allegedly scared women away. Prepare to stare into the abyss with the lonely wanderer of Sils Maria.
Plato

Plato remains the most famous philosopher in Western history, yet few people know that he started his career in the wrestling ring rather than the library. While we study his dialogues in universities today, he actually founded the very first university in the Western world. Furthermore, he invented the legend of Atlantis, which many people still believe serves as a historical fact. Prepare to step out of the cave with the student of Socrates.
Louvre

The Louvre stands as the largest art museum on Earth and a historic monument in Paris. While millions flock to see the smile of the Mona Lisa, the building itself hides centuries of secrets within its walls. For instance, the palace originally served as a fortress to protect the city from Viking attacks. Furthermore, during World War II, the curators emptied the entire museum and hid the masterpieces in the countryside to save them from the Nazis. Prepare to enter the glass pyramid of history.
