Aigio is a coastal city in the northern Peloponnese and is the second largest city in Achaia after Patras. Its port is now one of the 22 most important national ports, since it was one of the first cities to export goods to the rest of Europe and mainly to Italy. It counts 3,500 years of continuous habitation and has about 30,000 inhabitants, along with the surrounding communities.

Aigio was the first city to join the Greek state in 1821. The change in its image is significant. Events such as the great earthquakes of 1861, 1888 and 1995, the implementation of the new city plan, the flourishing of the raisin trade, the industrial upsurge and the First and Second World Wars are milestones in the development of its urban space. The aim of the present research work (NEOKLASIKI ARCHITECTURE IN AIGIO 1830-1940) was to locate original material, drawings, photographs closely related to the architectural physiognomy of Aigio during the years 1830-1940. The neoclassical architectural trends that prevailed at that time marked the city, in which several neoclassical and then eclectic examples appear. The most important buildings of this period are recorded. The buildings are separated into public, public facilities and houses. Each category is divided into subcategories. At the same time, there are very few remaining vernacular buildings from the time of the Turkish occupation. At the same time, the modern architecture of the interwar period appears with individual examples.
