This is a very interesting article, i like the way it entails different topics all embedded in the content. Topics ranging from the PROTECTION AND PRESERVATION OF SITES WITH GREAT CULTURAL HERITAGE.
And also THE STORY OF A DECORATED WAR HERO LIVING AN UNDERSERVED LIFE, i believe this portrays the worth of the country's institution which you mentioned..
I admire the way it entails LAW THAT WOULD PROTECT CULTURAL HERITAGE FROM THEIR OWNERS, Owners who are apathetic and shows no interest whatsoever in such a aesthetically appealing cultural heritage site. Because as you said its history belongs to all of us.
I believe the heritage site should be seized by the Croatian government and used for the purpose of the public, adequate atonement in the form of compensation should be provided for the family. Even though i am not sure the property owners will accommodate the idea of expropriation .
I believe the Croatian government can do this without the consent of the owners
