During the 6th century AD a small community of monks settled on the Inishkeel island. Their religious leader was Saint Conall Cael, from whom the island later derived its name. During the following centuries Inishkeel was a traditional destination of pilgrimages. Remains of the church and the connected buildings as well as some carved stones can be seen on the island. For its artistical and archeological importance the island was declared National Monument. A bell known as St Conall Cael's Bell remained on Inishkeel up to the 19th century and was then acquired by the British Museum.
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.
