1 week after people; In Rome towering above all else is the dome of St. Peter's Basilica. Reputably built directly above the tomb of St. Peter, the first pope of the Roman Catholic Church. Completed in 1626, the dome was plagued by structural problems from day 1, the base of the dome had started to crack, so steel support chains were installed and those still hold the dome together today. In the time of humans black cats were considered by superstitious people to be symbols of Satan, now in the absence of humans, they have colonized St.Peter's Basilica.
500 years after people; In the time of humans the dome of St. Peter's Basilica was considered structurally unstable so chains were wrapped around the base of the dome to strengthen the dome. Now after 5 centuries the steel support chains have corroded. Finally the support chains break and the dome of St. Peter's Basilica collapses.
