A place where history, culture, and nature blend into a perfect cocktail, Peru is every traveller's dream destination. If you're a history buff who seeks out heritage structures built by ancient civilisations, Machu Picchu in Peru should be on your bucket list. A 15th-century citadel built by the Incas on a lush green mountain ridge 2,430 metres (7,970 ft) above sea level sits at the heart of the Machu Picchu sanctuary that was enlisted as a UNESCO World Heritage Site in 1983.
