The Puente Nuevo in Ronda, Spain, is a dramatic structure used (quite naturally) as a bridge, but it has also served as a prison. The bridge was built to replace a previous bridge which collapsed, taking fifty lives with it. Obviously, the people of Ronda wanted a strong, firm bridge (who wouldn’t, after a disaster like that), so the castle-like puente was built. The architects took advantage of the bridge’s bulky structure by putting a chamber above the middle arch, which served as the aforementioned prison.
I’ve been working with pen and ink recently. It took me some time to learn to control a scratchy nib with ink on it, but now I find that I would prefer to use fountain pens over the usual pen. Writing is so much more beautiful when upstrokes and downstrokes vary in thickness.
