Ahead of the Colosseum and Pompeii, the towering Greek temple complex at Paestum near Naples is the first Italian archaeological site to reopen to tourists after the coronavirus pandemic lockdown.
A limited number of people are allowed on the site at the same time, they must disinfect hands and wear masks, and one-way routes have been marked out, said site director Gabriel Zuchtriegel.
It has also developed a free app to guide visitors through the sprawling site and send an alert when too many people are gathered in the same place.
