I walk by the (abandoned?) Samaritan Hospital for Women every day, it's such an interesting looking building compared to all around it and, in the midst of a heavily urban environment, almost looks completely wild, with flurries of green popping out of random spots on it.
Yes, but old buildings don't make for good hospitals, I'm afraid. They're hard to keep clean and in a sanitary state for operations and other medical procedures.
it's not weird that it's no longer a hospital, it's weird that it's no longer _anything_. The place looks like it was closed a decade or two ago and no one has even entered it since.
Plus it's a pricey location, despite being on what is effectively a busy motorway.
Another example of a very premium location/building abandoned for as long as I can remember is the building on the left of Cambridge House on Piccadilly.
