Seeing Jerusalem from both sides

.

For Weekend Reflections here is old and new Jerusalem reflected in a window on the Mount of Olives.
If you enlarge the photo you can see three arches which are inside the church. It would be fun if they were strange rainbows in the sky instead . . . .

Here is the same window as seen from inside the church of Dominus Flevit, another of architect Antonio Barluzzi's unique creations.
