Cultural valuables from most ancient times are frequently very fragile and have lost some parts. Today with modern methods we can help and cure a treasure, restore its lost parts, but only if we know what they looked like. You can study the treasure and say what you think it was and what it meant to the people who created it.
Regardless of the fact that each state protects its treasures with a special Law they also need your protection. Take a walk with your friends to the treasure, learn about it, clean the environment around. It will be grateful and will reveal before you its true shine and beauty.
