Ancient buildings in Mecca

""We are currently sounding the alarm, because unfortunately this is not the first destruction of ancient buildings in Mecca. During the last three decades, construction work to expand the mosque has already destroyed about two thirds of the sacred mosque's historical buildings." "And, while the house in which the Prophet was born has been transformed into a library, other sites have suffered worse fates: for instance, the house of Khadija, the Prophet's first wife and the mother of his children, was destroyed in order to build public toilets!"
