On Wednesday, archeologists revealed the remains of an ancient arts center underneath Rome dating back to 123 AD, according to the Guardian. Archeologists discovered the arts center during excavations for a new subway line to run through the Italian capital.
Emperor Hadrian is believed to have funded "the Athenaeum," as it was known at the time; it was a 900-seat complex created to promote arts and culture, CBS News reports.
"Hadrian's auditorium is the biggest find in Rome since the Forum was uncovered in the 1920s," said Rossella Rea, the archaeologist running the dig.
"We don't have funds for these kind of digs so this has come to light thanks to the new line," said Rea.
