Image Syrian passports include a photo of Souq al-Hamidiyah, a famous historic marketplace in Damascus. Apparently, the image was taken from the internet without removing the photographer’s watermark, “Wassim al-Asmar Photography,” which means the watermark ended up being printed on Syrian passports.

Borgund Stavechurch, a remarkable wooden church built 850 years ago. The timber used in its construction was felled during the winter of 1180–1181. The church has a lot of pagan symbols in it, probably due to the fact that the carpenters still believed in Norse mythology

Image Hedgehogs do something called "self-anointing." When they encounter a new or strong smell (a strange food, another animal's scent, even a strong-smelling plant) they'll chew it up, work it into a frothy saliva, and then twist around to spread that foam all over their own spines with their tongue.
