A choice of the answers:

• It has to be unique to the country or if it is not, it has to be astonishing compared to others .It has to represent history of the country.
• Something that is historical and different from the others, it has to have a special meaning for the world/country/pernor
• Something that is historically important or represents a special kind of design or intelligence that someone reached
• Its impact on society
• It should be a special location or object, different from the others. They should have an exceptional value and a remarkable kind of beauty with some history behind it.
• They should have been around long enough that they represent something important. They should have made an impact on the society or have influenced a place's history in some way.
• They must be objects not common for other countries or regions, (like the human castles in catalonia) and they must identify the people too.
• Cultural and natural object shoud be on an oficial heritage list acording to if they are special and about their history, depending on if they have a unique geographic situation or a cultural aspect that should be kept.
• These objects should be representative and unique, also they may have something special or a history behind, so it's important and has a reason to be remembered and conserved.
• It should be something, which units more than two generation like some movies.
• It has to be old & has got an important history
• something old, important in history, beauty
• I think it is all about how old the object is or how important it is for the history according to the antiquity, the complexity and the beauty
• I think that a language like English would be a good criteria.
• They should have a generation-spanning history
• It is something important like when you think about the country you think about that like the Brandenburger Tor. It is not in the heritage list but that should be in the heritage list.
• They should be measured by the value of all and how important they are to our future or how
• If it important for a lot people or has a long history, than it has to be on an official heritage list.
• I think an object should be on a heritage list when it´s a fundamental part for many people or the history of the country (like the wall of Berlin which isn´t a heritage site yet).
