In ancient Rome, the hortus was initially the small plot of land used for growing vegetables. One of the first practical cultivation manuals by Marcus Porcius Cato, De agricoltura, dates from this period.

In the Middle Ages, various vegetable crops were cultivated in monasteries, a practice that has continued to the present day. This typical medieval garden took the name hortus conclusus, from the fact that it was a garden enclosed by four perimeter walls.

The Renaissance saw a transformation of the vegetable garden into an ornamental garden in which aesthetic considerations prevailed over agricultural and productive ones.

In the 19th century the vegetable garden began to take on its present-day configuration as a result of population growth and the increasing demand for food.

In recent years, due to the desire to eat healthy and organic food, there has been a growing demand for small plots of land that can be cultivated independently, even in cities. Local administrations are therefore increasingly prodded to find and transform small urban voids into vegetable gardens with the dual purpose of nurturing the social function of small-scale agriculture and improving civic life and the environmental and landscape quality of the city.

The vegetable garden in the Italian pavilion is therefore a meeting place and social hub where initiatives and activities are organized to share a cultivable space. In the pavilion's vegetable garden, as well as being able to touch typical Italian horticultural products, it will be possible to share.
