Built between the 1st and 2nd centuries AD, The Roman Amphitheatre of Venosa was deprived of many works and ornaments, which are currently located in other monuments in Venosa (many were used to erect the adjacent incomplete church). The first excavation was commissioned in the 19th century, where a series of bronzes, coins, and terracottas were found, but due to neglect, the ruins were buried again. Only in 1935 was everything brought back to light.
The Roman Amphitheater has an elliptical shape, with three levels, partly built above ground and partly created by terracing the ground on which it stands. The major axis measures 70 meters, while the minor axis is 40 meters. Based on these measurements, it is believed that this structure could accommodate approximately ten thousand spectators in its time. The lowest level is that of the arena, where the terrace of the 'podium' for important figures is located. There are two additional levels, supported by three concentric ambulatories.
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.
