Built in the early 17th century by Henri the Fourth, and designed by the architect who created Place des Voges, Hopital St Louis is still a working hospital. Built outside the city gates it was intended as an isolation hospital for plague victims, and contained its own gardens and chapel to nourish the bodies and spirits of its residents. Here is how it looked way back when.
The principal entry gate is currently famous as a police station in some french tv drama. That's it at the bottom center of the etching to give you some sense of scale.

Central courtyard pavilion. you can see the strong resemblance to Place des Voges
The Bath Pavilion. I'm not sure but this may be a later addition.
The Chapel exterior
The Chapel interior, ransacked during the revolution and never completely recovered. A woman here who is a member of the friends of St Louis told me that during roof restoration a decade ago, they found the original chapel bell, which had never been rung, and was then hung and now rings on mass days.
The bell at the entry gate, which also had a circular rotating mechanism that allowed people to pass food and things into the hospital without entering or touching anyone within.
