Loyalists in East Belfast staged bonfires on Saturday, in an annual tradition known as the 'Eleventh Night'.
Small gatherings were seen at the events, as firefighters patrolled the areas to control the blazes.
As part of a commemoration of William of Orange's victory at the Battle of the Boyne, the event precedes celebrations and parades on the Twelfth of July.
This year's parades, usually organised by the country's Orange Order, were cancelled due to large crowds and the potential spread of coronavirus. The Order also discouraged bonfires, which take place spontaneously throughout Ulster.
