Our knowledge regarding the urban planning of Aquileia and its development has significantly increased since the publication of the last comprehensive overview of this subject in the volume Aquileia moenibus et portu celeberrima in 2009. Indeed, over the previous decade, several new research projects have shone new light on the urban planning, function, and development of Aquileia, adding much new data and evidence to our overall knowledge of the ancient colony and Adriatic emporium. This paper presents the most significant results of recent investigations, providing a first updated overview of the city’s urban development, focusing and commenting on the following themes: city walls and town planning, Forum and river port, entertainment and recreational buildings (theatre, amphitheatre and Imperial baths), commercial areas and complexes, private spaces and townhouses.
