Countries and World Heritage Sites I Have Seen to Date

I have seen a lot of travel for a twenty year old and have absolutely no intentions of stopping any time soon.
At the moment, I have been to nine countries, not in order: Austria, Canada, England, France, Germany, India, Ireland, South Africa, and, obviously, the USA.
According to UNESCO's (The United Nation's Educational, Scientific and Cultural Organization) list of World Heritage Sites, I have seen the following:
In the US: The Statue of Liberty, a cultural site
In England: The Tower of London and "Wesminster Palace, Westminster Abbey and Saint Margaret's Church," all regarded as cultural sites
In S. Africa: Robben Island, where Nelson Mandela was imprisoned, a cultural site
In Germany: Heidelberg Castle and Old Town, on the tentative list for cultural sites
In France: Banks of the Seine, Cathedral of Notre-Dame, Former Abbey of Saint-Remi and Palace of Tau, and the Palace and Park of Versailles, all considered cultural sites.
In India: I have already seen Humayun's Tomb and will see Agra Fort and the Taj Mahal, both in Agra and both cultural sites; I will see Qutb Minar and the Red Fort complex, both in Delhi and both cultural sites; I will also see the Jantar Mantar, which is in Jaipur, the "pink city," which is also considered a cultural site.
Besides these sites in these countries, I have seen many more and will continue to see more in the future.
