For today's Geo Quiz -- we're looking for an Arab emirate. This sandy desert peninsula looks out on the Persian Gulf.
It's an oil rich nation and it's the one that launched Al Jazeera. About a third of its one million residents practice a conservative form of Islam -- like the country's neighbor, Saudi Arabia. Saudi Arabia forbids any house of worship that isn't a mosque.
But the country we're after has shown a more moderate approach. Its emir granted the Catholic Church land in the desert outside the capital, Doha to build a church.
It's the first church to open here since the arrival of Islam more than a thousand years ago.
We'll pay a visit to the Islamic nation's new Christian house of worship, but first try and name this country at the edge of the Persian Gulf.
