In 1770, the first agricultural and industrial fair was established in Oeiras, representing a unique national event that also contributed to the creation of fishing shelters and a new customhouse and factory, among other projects. One of the principal developments was the construction of the estate of the Marquess of Pombal, which today exists in its original form, with garden, palace and agricultural dependencies, such as the wine cellar, barn and other buildings, today housing the national institutions responsible for bio-science.
