Sintra, Portugal, is a UNESCO World Heritage site known for its fairytale-like atmosphere and deep history. A fun fact is that Pena Palace was designed by King Ferdinand II, an artist-king who combined Moorish, Gothic, and Renaissance styles into a wildly colorful masterpiece. Beneath the gardens of Quinta da Regaleira, there is a secret network of tunnels and "Initiation Wells"—subterranean towers used for symbolic Masonic or Templar rituals. Interestingly, the lush forests surrounding the town are actually man-made; they were designed in the 19th century as a romantic landscape planted with exotic trees from around the world. For foodies, the "travesseiro" (pillow) is a protected local pastry whose original recipe is a closely guarded secret only sold by licensed bakeries. Finally, just a short drive from Sintra is Cabo da Roca, the westernmost point of mainland Europe, which was once believed by ancient mariners to be the literal edge of the world.
