Patticake - The Grenfell fire was a real tragedy and the government and local authorities should have been doing something about it. Money was given but it has been very slow to disseminate it. But, we are on this earth for a short time. Buildings like Notre Dame which have existed for hundreds of years are a testament to the thousands of people who have worked on them, whether artists, craftsmen or labourers. Churchill understood the importance of such buildings during WW2 when he sent word that St Paul's should be protected at all costs because he believed it would be devastating for morale if it was destroyed. This was at the height of the blitz.
The renovation of Notre Dame, however it is carried out, will provide good quality work for skilled craftsmen and also an opportunity for young people to learn a craft.
Craftyone - I can't believe that people still believe in plenary indulgences. You can have little or no idea of what other charitable causes these donors support. Some chose to help the poor (Bill and Melinda Gates Foundation) and others chose to support the arts. Some chose to do both - such as the Tate family who, in addition to the Gallery, funded the building of libraries.
