The Parque de la Reserva was originally opened in 1929 to commemorate all the civilian reservists who fought in the defence of Lima during the War of the Pacific. But more than 65 years later Parque de la Reserva became one of Lima's most visited tourist attractions.
In May 2007 a water and light show called the Circuito Magico del Agua (The Magic Water Circuit) was inaugurated. The Magic Water Circuit has the world record for the largest fountain complex in the world, displaying 13 distinct fountains and many are interactive.
All of the fountains are illuminated at night, many with continuously changing color schemes. A colorful laser light program synchronized with classical and Peruvian music makes the fountains sparkle and shine as the water flows in unique patterns and shapes.
