Prague and Petřín

Much like Manhattan’s Central Park, Prague’s Petřín is (in part) a demonstration of the will and effort required on the part of a city to maintain green spaces. Once they become part of the city’s identity (as in those aforementioned cases), they exist in a space orthogonal to modern real estate development.

Charles Bridge

Prague’s Charles Bridge is centuries-old, covered in statues, and seemly perpetually mobbed. We visited during the off-season (November) and never saw the bridge without plenty of company. Perhaps the best part of the visit, though, was staying adjacent to the bridge in the Smetana Hotel, looking out over the Vltava (and crossing the bridge on many of our adventures around the city.)

From up close, the hotel is easier to find, but small triangle park across the street from the hotel is still not visible from this angle, making the the geometry of the ground floor and the street outside escheresque.

Sodium Emission vs. Rayleigh Scattering

We’re not far from the ninth anniversary of the founding of Decaseconds, and I came upon this arresting image of Berkeley Marina, the Marin Headlands, and the Golden Gate Bridge (never before published here) while searching for just the right anniversary shot. I’m fascinated by the way the orange emission of sodium vapor lamps lighting Berkeley (I’m sure now all swapped for white LEDs) matches the Rayleigh-scattered oranges of the winter sunset. The same wavelengths of light, coming from completely different mechanisms.

Verticality in Prague

The compactness of European cities, particularly ones like Prague that are situated in valleys, leads to these kinds of spectacularly vertical spaces. Each street seems to be stacked nearly on top of the next.

Vertical Walls Beneath the Castle

On the hilltops above those city streets, inside Prague Castle, the space continues to be used efficiently.

Inside and Outside the Castle II

Above the castle structures, the spires of St. Vitus Cathedral continue the verticality.

Today’s image falls into the category “How have I not posted this already?” This image of a supermoon aligning with the Route 11 principal axis of Canton, New York has been used in the table of contents of St. Lawrence University’s magazine, as well as in several blog posts. In spite of that, I’ve apparently (according to Flickr’s camera roll feature) never shared it to Decaseconds.


Around Prague Castle

St. Vitus Cathedral is at the heart of Prague Castle and just as grand as words like “cathedral” and “castle” imply.

St. Vitus Cathedral

Inside was thoroughly saturated with visitors.

By comparison, much of the rest of the castle seemed empty. Given that this was the winter “refresh and repair” season, we weren’t surprised.
