The production centres established in Late Antiquity proclaim how serious changes come through the whole Roman world. Pressing facilities established in this time period are usually very different in construction; old methods have changed and very often less quality materials were used.
Also the location has entirely changed - now we can find pressing facilities also in cities. In unstable time period of 4th century people from countryside searched for safety in fortified cities.
The production of olive oil and wine was very important for the local economy and trade and removed to cities as well. Agricultural functions until then characteristic for villae rusticae are now present in cities.
This phenomenon is called rustification of urban life. Second change occurred in spiritual sphere.
During 4th century, Christianity became the official religion. With the great change of religion came the significant change of conception of olive oil and wine.
Both liquids now built a part of liturgy. The consumption of wine and olive oil increased, new production centres were demanded and from that moment, pressing devices were built in cities in the vicinity of churches or as a part of other religious buildings.
In Histria only 4 production centres were established in Late Antiquity: Parentium, Fažana, Nesactium and so-called Castrum in Dobrika Bay at Brijuni Islands. In Dalmatia 13 production centres were built in Late Antiquity.
Most of them are located in Colonia Martia Iulia Valeria Salona and in its vicinity. Outside the Salona region are sites at islands: Brač, Majsan and Lastovo.
