Thousands of people attended the annual Relief of Derry commemorations in Derry/Londonderry on Saturday, as members of the Apprentice Boys and visiting bands followed the traditional programme through the city.
BBC News NI reported that more than 7,000 Apprentice Boys members and 124 bands took part. The main procession began around lunchtime, following morning events on the historic walls and a service at St Columb's Cathedral.
The day marks the ending of the Siege of Derry in 1689. This year's event was the 337th anniversary of the conclusion of the 105-day siege, one of the central historical commemorations in the Apprentice Boys' calendar.
The Associated Clubs of the Apprentice Boys of Derry says the annual August programme begins at midnight with a cannon fired from the walls. The eight parent clubs then make a morning circuit, followed by a wreath-laying in the Diamond. A pageant recounting the events of the siege takes place before the main parade.
Participants and spectators arrived in the city from across Northern Ireland and farther afield. The scale of the gathering required traffic controls throughout Saturday, and police had advised motorists to expect delays while processions moved through the city centre and Waterside routes.
The programme concluded with the parent clubs returning their colours to the Memorial Hall within the walls. The Relief commemoration is held on the second Saturday in August each year, while a separate December event marks the shutting of the city gates at the beginning of the siege.
