First of all, congrats to the winner @magnata ! The photo really looks effortless and cozy but beautiful at the same time. So, here is mine:

This is my photo from a place that I was really shocked and impressed. Here is the Sedlec Ossuary, a Catholic chapel in Kutná Hora. Inside of this church is made by human bones! It was an amazing feeling to see that. Sounds scary but I felt such a relief and peace in there.
