However, there is another story to be told that is largely overlooked. This lecture covers the background to the very existence of the city, the materials it is built from and where those materials came from and, most significantly, how those early decisions of the 15th century are directly responsible for the vast scale of conservation problems seen today. It is entirely possible that the city may never be saved and that we may count ourselves lucky that we can experience it now. Future generations may not be so lucky. This lecture provides a totally new and fresh insight into Venice that even the most experienced and frequent visitor may not be aware of.
