These are the most unusual churches we have ever seen.
1. Top left. Goreme, Turkey.
We are not sure when this was built but it is definitely ancient.
The Cappadocia valley where this church stands is very popular for it's rocks. The people of this village also carve out houses, churches and monastries.
2. Middle. Duomo (Milan Cathedral) Italy.
This church looks massive and strong and almost evil and scary. Though that could just be the angle of the photograph.
But it is utterly amazing.
3. Bottom. Halligrimur, Iceland.
This church is very unusual. It is 74.5 metres (244ft) tall. It is the fourth largest architectural structure in Iceland.
