About an hour from Paris is the pretty gothic town Chartres, with its ancient cathedral.
I took the train out and hoofed it around town one day last fall (hence the green). It was lovely, if not a little uninspired. There's not a whole lot going on aside from the church, but the tourist office gives you a nice map to explore the rest of the town on foot.
Many of the stained glass windows are original from the 13th century, and a gorgeous shade of blue.
Well, that's uplifting.
The day was flat and overcast, so I put some filters to use to make things a bit more interesting and contrasty.
How very goth.
