Between 1993 and 1996, several archaeological excavation campaigns at the site of Las Eretas partially unearthed the urban fabric of a fortified village from the Early Iron Age, the most significant structural remains of which included the wall and towers that defended it, and several dwellings built around a street and public square which facilitated pedestrian traffic inside the fortress.
The protohistoric village with its houses dates from the 6th to the 4th centuries BC and are typical of the Urnfield culture. Today there is a museum where thematic areas have brief text with illustrations – maps, photographs and drawings –, and a display cases showing original archaeological pieces, both from the Las Eretas site and other Navarrese Iron Age villages which have been investigated.
References:Duino Castle was built by the Wallsee family in 1389 on the cliffs overlooking the Gulf of Trieste. It replaced an older castle from the 11th century. Over time, the Wallsee family disappeared and the castle, after having been used as a prison, became the residence of the Luogar and Hofer.
At the end of the 19th century it became the property of Prince Alexander von Thurn und Taxis from the Czech branch of the House of Thurn and Taxis. It remains with the family to this day with his great-grandson Prince Carlo Alessandro della Torre e Tasso, Duke of Castel Duino the current owner. The castle has been opened to the public as a museum and park.
