Queen's University, Kingston:

Closeups showing limestone cladding. Almost all buildings at Queen's are cladded in limestone, even the new ones (the building on the left in the second picture was built in the 1990s).
This one is my favourite from a context perspective. It shows how Queen's is located in a central urban setting yet still outside the CBD (Queen's is in the lower left, downtown in the centre-right)
