Royal Botanic Gardens, Kew

#europetrip The Palm House is, without a doubt, the crown jewel of Kew Gardens. This colossal Victorian glass and wrought-iron structure is a masterpiece of 19th-century engineering, transporting you immediately into a humid, lush tropical rainforest. Walking among the towering palms, ferns, and exotic specimens from across the globe—including the world's oldest potted plant, a massive Jurassic Cycad—is an immersive experience. The steamy, dense air and the sound of dripping water complete the illusion. Tip: Don't forget to climb the spiral staircase to the upper walkway for a unique canopy-level view of the entire house and its incredible collection. An essential, breathtaking piece of botanical and architectural history on any London #europetrip.
