The three pictures are all of the same very large shrub. To me the leaves look like a Magnolia, but it is huge, just under the height of a single storey building. It is coming into flower now - in July - whilst normal sized Magnolia planted in Kent UK - in domestic gardens flowers about April or May. The location is in a courtyard setting. The shrub looks very strong and healthy-with little or no attention given to it. Is it a Magnolia or something else?
