Which castle in the province of Trieste, north-eastern Italy? The place is noted for being the place where the physicist Ludwig Boltzmann died and for inspiring a poetry masterpiece.

Obviously I was inspired by the previous question

Rielke wrote Duino Elegies in Duino, of course.

This Duino castle belong to one very famous and well-known European noble family. To which one?

Its cant be so hard, because owner of this castle in this times was a well-know patroness of Rilke, this is reason, why Rilke live in the castle seven month in 1911-1912 and start writing the "Elegies".

More clues. From 16 to 19-th century this family had own postal services around the Europe and even own postage stamps. They owned brewery and gave family name to beer-brand (sold to Paulaner in 1996, but still produces beer under family name). And name of this family comes from Badger on their coat of arms.

I had a pleasure to ask this family in Jüri, 2006, September 13th, question 29 if I am not mistaken.

Oh yes, now I remember it. You really asked about this family. And I answered. Now can we change places. Seems to me, that only two of us know about this family in Estonia One more clue for others: besides postal service, this family offer one more public service in medieval time, now in many languages name of this public service called by this family.

There is a board game inspired by their postal service: Thurn und Taxis

Thurn und Taxis (German branch of family) or Torre e Tasso (Italian Branch, owners of Duino castle)) are correct

Whose monument?

Located in the town of Sligo
