St. Nicholas' Church stands besides one of Germany's oldest manmade waterways, the Frischen Grube, and was dedicated as the church for sailors and fishermen. The 37m high nave is almost the height of the Marienkirche in Lübeck. The protruding northern and southern vestibules that resemble the arms of a transept are also a particular feature of the church. The lavishly adorned southern gable takes a special place in art of brick construction due to its wealth of glazed figured bricks. From St. Nikolai's medieval interior decoration survives a late-thirteenthcentury granite baptismal font and a maritime altarpiece made in the early nineteenthcentury, but the church's interior is chiefly characterized by completely preserved baroque furnishings.
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.
