Following the disastrous fire of Notre Dame de Paris, heated discussions are taking place in France to decide on how to restore our cathedral.
There are many ideas, with two rough camps: the ones who want an exact replica (or something aligned with the style of the bygone part), and the ones who want a contemporary addition (a glass tower for instance).
When listening to the discussion, people in the latter camp mention that every time there was an update of a church (following an accident (fire, construction), or when making it bigger) the changes were contemporary for that time, and raised controversies because traditions were not kept.
Was that indeed the case? I would mostly be interested in major West European churches first (for the sake of the Notre Dame discussion), but any similar building (that is something which holds a traditional symbol, such as a university for instance) would be fine too.
