My first view of the Eglise Saint-Eustache was this
across a construction site at Les Halles.
It's much easier to get a sense of scale from a distance - when you're up close it's impossible to frame.
Inside it's a rival of Notre Dame
The best part - there's only a fraction of the tourists here and they are generally far better behaved.
