A parade by the Apprentice Boys through Londonderry's city centre has passed off largely without incident.
The parade is an annual event
However, there were minor scuffles when police arrested a loyalist youth.
About 2,500 Apprentice Boys and 20 bands paraded through the city before and after a religious service at St Columb's Cathedral on Saturday.
Nationalist and loyalists were separated by lines of police as the annual Lundy's Day parade passed through the city centre.
The parade marks the 316th anniversary of the shutting of the city's gates by 13 young apprentices against the forces of the Catholic King James II in 1688.
Colonel Robert Lundy is reviled by loyalists as a traitor.
He was governor of Derry when the city came under siege from King James' army and his notoriety stems from his efforts to persuade the defenders to surrender.
During Saturday's some missiles were thrown after the main parade and there were scuffles in the Diamond area.
Police described the incidents as minor.
Three people were arrested for disorderly behaviour.
Most shops opened up in the city centre this year as security measures were scaled down.
However, some traders closed early after the disturbances.
Recent years have seen little trouble at the event, after agreement was reached between the Apprentice Boys, the nationalist Bogside Residents' Group and the business community.
Last year, the police said it was one of the most peaceful parades in recent times.
Chief Superintendent Richard Russell, the Foyle district commander said: "I am pleased with the way today's events have gone. The parade was largely peaceful, and the city remained fairly normal throughout the day."
