It was realized excavations in the end of 80s and beginning of 90s, of the last century, in the area called Torre del Pedernal, that had not continuation, leaving the ruins fenced, but abandoned.

The Celtiberian Bursau and the Romanized Bursao

The Celtiberian Bursau, mentioned by Ptolemy, as Bursada, among the Celtiberians, possibly belonging to the Lusones. The mint house that minted bronze money, aces and its divisors, from the middle and the end of the 2nd century BC., with manly head in the obverse and lancer horseman with helmet in the reverse (aces) or horse galloping (divisors). Later it was romanized as Bursao, being mentioned by Plinius and Livius making reference to its inhabitants as Bursaonenses.

It is possible that the origin of the Celtiberian occupation was in a little settlement of the beginning of the Iron Age in La Cueva Esquilar. Later, fom the 4th and 3rd centuries BC., would take place the origin of the Celtiberian city spreading out through the hill of La Corona and, from the 2nd and 1st centuries BC., through the zones of La Torre del Pedernal and Poligono of la Romeria and in the proximities. Also in these zones around the hill of La Corona the ruins of the previous Roman city of Bursao have been found.

Archaeological Museum of Borja

This museum is located in the old parish Church of St Miguel, of Mudejar Aragones style, restored and fitted out to the effect. This project is fruits of a collaboration agreement between the council town of Borja and the Centro de Estudios Borjanos, big cultural promoter of Borja and its region.

This centre has as laudable objective to increase the value of the rich archaeological patrimony of Campo de Borja from the Palaeolithic to the Middle Age with special attention to the materials coming from the Celtiberian-Roman city of Barsau.

The museum proposal is structured in 13 showcases and several exempt pieces coming from the Palaeolithic, the lack of Neolithic ruins obliges to jump to the Chalcolithic following through the Bronze Age, the First Iron Age, Celtiberia, Roma, the Islam and the Christian Middle Age to end the route showing “The Jewish sign”.

  • Showcase 7: One of the showcases is dedicated to the contacts with Rome through the commerce, represented by ceramics imported from Italy and the war with catapult projectiles, lead projectiles or symbols of Celtiberian equestrian dignity.
