In January of 2014, I visited the Ethiopian city of Lalibela. We were there over the Ethiopian Orthodox Christmas celebration, when tens of thousands of pilgrims filled the streets and churches.
I put together a Magcloud publication called Christmas in Lalibela that goes into much more detail about the history of Lalibela, the experience of being there, and my personal concerns about objectification.
You could certainly purchase a copy of if you like; however, you can also read the whole thing online, absolutely free.
I went back four years later. The photos are very different.
