All eyes are on the UK as Britons head to the polls to decide whether they want to stay in the European Union, or leave.
On the continent, the vote is being watched with much concern.
The EU has already been tested to its limits in recent years by a series of financial crises and by the unprecedented movement of refugees and migrants. But if Britons vote to leave, it could prove to be the EU's biggest challenge since its founding.
The problem for European officials is that the anger driving anti-EU sentiments in the UK, also exists elsewhere on the continent. A recent Pew survey polled 10,000 people in 10 major EU nations. And it found "Euroscepticism" is on the rise.
So, after decades of existence, what's the future of the EU?
