According a tradition collegiate church of Our Dear Lady of the Old Chapel (Alte Kapelle) dates from Roman times. In the 18th century the Romanesque basilica was magnificently rebuilt in the Bavarian rococo style. Of special interest is the new organ which was dedicated by Pope Benedict XVI in 2006 during his visit to Regensburg.
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.
