Photo Of The Day: A Plus Cathedral

Photo of the day: Rio de Janeiro cathedral
Today is March 14, also known as Pi Day (in case it’s been awhile since you took math, pi is the ratio of a circle’s circumference to its diameter, 3.14), a day to celebrate mathematics, or just eat some pie. If you are in Cambridge, Massachusetts, today and can remember a good portion of the many digits of pi, you might get to eat some free pie. Today’s Photo of the Day by Flickr user autisticglobetrotting2010 is a bit math-inspired: the cross at the ceiling of Rio de Janeiro‘s San Sebastian Cathedral hints at a plus sign. The modernist cone-shaped church is highlighted by four enormous stained glass windows that form at the top with a cross. Designed to echo the Mayan pyramids, the distinctive structure is hard to miss in the Rio skyline.

Share your travel photos in the Gadling Flickr pool for a future Photo of the Day, and happy pie-eating!
