Lima is the capital of Peru, and with around 9 million people living in the area, by far the country's biggest city. Since the arrival of the conquistadors of the 1500s, the city has played a role in Spanish Colonialism. More recently, it has exploded in both size, as it expands into the mountains, and population, as Peruvians from the countryside come to the capital seeking opportunity. Most, in actuality, have instead found poverty.
Taking your security into account is a must in Lima, granted, this is true for any big city anywhere else in the world too. Lima is also a city of eternal fog, with a calm pacific mist blanketing the city nearly 24 hours a day. There are historical sights dating back to the days of the first conquistadors, catacombs with skulls and bones, romantic oceanside walks, and terrific cuisine. Enjoy the tour.
