May 2023, nine tombs dating back to 9,000 years ago were discovered

during a restoration project on Via Laietana, a major road in Barcelona. 

The tombs were found in a well-preserved state, 

and they contained the remains of both adults and children. 

The tombs are the oldest archaeological finds ever made in Barcelona, 

and they offer a rare glimpse into the lives of the city's earliest inhabitants.
