During the announcement, Raggi said that the newly appointed architect has previously worked with her party.
Montuori is a highly regarded urban planning expert who served as advisor to a former centre-left mayor of Rome, Walter Veltroni.
"I don't deny my centre-left past," he said.
Montuori is expected to oversee the radically revised and downscaled Roma stadium project, as well as a range of schemes to upgrade Rome's rundown outskirts.
The new planning chief is an associate professor at Roma Tre University and former chief of staff of deputy mayor Luca Bergamo.
