Tens of thousands of people are expected to descend on Belfast later - for the city's annual Pride parade.
This year, more than 180 groups are taking part in the parade and organisers are trying to exceed last year's record of 55,000 attendees.
And for the first time ever the rainbow flag is being flown from City Hall.
The rainbow flag was delivered down Belfast Lough on a flotilla of boats blasting their horns to cheers from onlookers on the banks yesterday evening.
Belfast Lord Mayor, John Finucane, helped erect the flag at City Hall early this morning.
At the break of dawn, I was proud to help raise the Pride flag over City Hall for the very first time in our history.
This is hugely significant for Belfast.
I wish everyone taking part in @belfastpride a brilliant day.#RightsNow

Mr.Finucane will be leading the parade at 1pm.
He says there is an increased route along with a record number of floats.
Lord Mayor Finucane also says there will be 'an inclusive message along with vibrancy and diversity'.
The Rainbow flag was also raised in some other landmark locations around the city including the Harland and Wolff shipyard.
