National Museum in Warsaw. Due to the lack of extensive archaeological surveys, no
Iron Age settlements connected with this people were ever found in the area. Nevertheless, analysis of numismatic finds from the
Jalón-
Tajuña (ancient
Tagonius) area has led some archaeologists to relate the
mints of three unknown Celtiberian towns –
Aratis/Aratikos,
Titum, and
Titiakos – with the Titii, pointing Titum as their presumed capital. It was only in 2016 that the town of was rediscovered and identified with the
Iron Age site of Castejón I – El Romeral at
Aranda de Moncayo in
Zaragoza province. Between 1993 and 2013, the five-
hectare site was plundered by
Ricardo Granada Pérez, a local
retiree turned
treasure hunter who, by using
metal detectors and a
GPR, illegally excavated 4,000 archeological artifacts dating from the 3rd to 1st centuries BC, including a set of eighteen celtiberian helmets of the Chalcidian type (a.k.a. Iberian-Celtic or Hispano-Chalcidian; that were smuggled out of Spain and sold at auctions held in
London and
Oberhaslach in France. Out of this total, sixteen helmets were bought by the German building contractor and collector of antique weapons
