The back of our barn, with its three 13th century windows (mullions removed who knows when, the central one converted into a door, the right hand one greatly reduced).
UPDATE: Simon has checked the Histoire de la Ville et du canton de Preuilly by Constant Moisand (1846) and he has this to say:
L'Eglise de Saint-Nicolas était située dans le faubourg de ce nom : ce qui prouve, c'est que le champ qui l'avoisine porte encore aujourd'hui le nom de Champ de la Cure. Cet édifice, après avoir été converti en hôpital, a passé dans des mains privées bien avant la Révolution. On croit que sa seconde destination intéressait les lepreux, et que c'était une maladrerie, institution du XIIIe siècle, commune à toutes les villes...
My translation: "The church of Saint Nicholas was situated in the suburb of the same name. Proof of this is that the surrounding field still bears the name 'Field of the Cure'. This building, after having been converted into a hospital, passed into private hands well before the Revolution. It is believed that the second designation would have benefitted lepers, and was a clinic, an institution from the 13th century, common to all towns..."
Curiously, our barn is not mentioned at all in this book. I don't think what he says really offers proof that Saint-Nicolas was the leper hospital, but neither would I discount it. We can't find any evidence, for instance, that the field he talks about (presumably the modern plan d'eau) was known as the Champ de Cure. It is not named as such on the 1813 cadastral map. I assume he is indicating that the field was associated with the presbytery, but the word cure has two meanings. It can be either a living (religious) or a treatment for a disease. If the field was known as the Champ de Cure, perhaps the two meanings got conflated somewhere along the line. His sentence about the leper hospital is in rather old fashioned language and I have translated what I think it means, but others are welcome to refine it and let us know.

Bizarre Presidential Accidents: I know I shouldn't laugh, but today is the 95th anniversary of the date that President Paul Deschanel was found wandering along the track late at night in his pyjamas, after having fallen out of a window of the presidential train at Montargis. You can read a little about this charismatic and eccentric French politician here. There is an amusing French language account of the incident here. I first heard about him by watching an episode of the French equivalent of 'Celebrity Who Wants to be a Millionaire' on telly.
