It's been an eventful 400 years – tumultuous and industrious in equal measure.
Belfast bears little resemblance to the town it was back in 1613 when it had a population of just 200, no bridges and was perched on a sandbank.
But the Royal Charter granted to the town four centuries ago this year laid the foundations for the city we know today.
And the moment is being celebrated in a programme of events.
The Belfast 400 festival is taking place over four days at Easter with a fun-filled programme to mark the 400th anniversary of the Royal Charter granted by King James I in 1613. Belfast was declared a city in 1888.
