Portugal
In 27 BC, Lusitania gained the status of Roman province. Later, a northern province of Lusitania was formed, known as Gallaecia, with capital in Bracara Augusta, today's Braga.
There are still many ruins of castros (hill forts) all over modern Portugal and remains of Castro culture.
Numerous Roman sites are scattered around present-day Portugal, some urban remains are quite large, like Conímbriga and Mirobriga. The former, beyond being one of the largest Roman settlements in Portugal, is also classified as a National Monument. Conímbriga lies from Coimbra which by its turn was the ancient "Aeminium"). The site also has a museum that displays objects found by archaeologists during their excavations.
