Ruins are the remains of structures built by the Old Ones. They come in two types: Ancient Ruins, which are exposed locations known to the tribes, and Ruins, which are well-preserved facilities that the tribes have rarely or never entered.
A millennium before the events of Horizon Zero Dawn, the Old Ones had become quite advanced in the construction of machines. By the 2060s, they were used for transportation and entertainment purposes (i.e. Focus devices and advanced aircraft and land vehicles.) However, the environmental situation was at an all time low. These conditions led many manufacturing corporations like Faro Automated Solutions to construct armed machines for peacekeeping purposes. Conditions worsened when the Faro Plague began. Cities were used either as recruiting stations or as collateral damage during Operation: Enduring Victory. At the same time, bunkers were built to help make installations or for the military, as well as for Project Zero Dawn.
Once the Plague wiped out all life on the planet, the cities, now in ruins, went unused and began to rust away. When the new human population left the Cradle facilities, they found the cities unnerving or foreboding, and began to build new settlements, leaving the structures to decay.
