Declared a National Cultural Heritage of the Colonial and Republican periods, the park was inaugurated on November 24, 2004. It covers an area of 25,000 m2 – of which 6,000 m2 are of green areas, raised on two levels and with clear views of the Rimac River. It received this name because it was built to house the remains of the "Wall of Lima", which was built by the viceroy Melchor de Navarra and Rocafull with the purpose of protecting the city from uprisings and to control the commerce that entered the city. In addition, it was a clear border between the urban and the rural and to protect the city of possible attacks of the enemies of the Spanish crown in XVII century. The building was built mostly in stone and baked bricks. Located inside its premises one will find a restaurant, playgrounds for children, amphitheater with capacity for 2,500 people and craft shops.
