Jose Carreras entertained the crowds in London's Hyde Park
The BBC Proms season has ended with the traditional Last Night concert in London's Royal Albert Hall.
Thousands of people also attended open-air events on big screens in Hyde Park, Belfast, Glasgow and Swansea.
Jose Carreras and Lesley Garrett performed at Hyde Park, while Bryn Terfel sang Rule, Britannia at the Albert Hall.
Sir Roger Norrington, conductor of the Stuttgart Radio Symphony Orchestra, conducted the BBC Symphony Orchestra.
The National Youth Choir of Scotland were among the acts on Glasgow Green, while the BBC National Orchestra of Wales appeared at Swansea's Singleton Park, and the Ulster Orchestra were at Belfast's City Hall.
It is 40 years since Sir Roger's Proms debut but the first time he has been the conductor of the final night.
Patriotic favourites including Pomp and Circumstance, Rule, Britannia! and Jerusalem were played, with the traditional conclusion of the national anthem.
Works by Beethoven, Wagner, Puccini and Verdi were also performed and there was a celebration of folk music with an arrangement by Chris Hazell of traditional compositions from around the UK and Ireland.
Also in the programme was Sea Songs by Vaughan Williams, as this year's Proms have celebrated the music of the British composer, who died 50 years ago last month.
Asked earlier if he was nervous about Saturday evening's concert, Sir Roger replied: "A little. It's rather daunting, isn't it?"
He described the occasion as a night "when classical music lets its hair down".
"Classical music in the last eight weeks has had this glorious festival in the Albert Hall and around, and it goes on being glorious - but it becomes pretty barmy by the end," he told BBC Radio 4's Today programme.
"The Proms attendance has been fantastic this year - amazing.
"If you wandered around Kensington Gore in the evening this summer and see these thousands of people pouring out, you realise classical music is alive and well in London."
Patriotic displays are always seen at the final evening of the Proms
He said those who attended the Proms had "such a great time" and hailed the "extraordinary feeling of community" among those inside the Royal Albert Hall.
The BBC said this year's event has been a success, with 78% of the main evening concerts selling out.
The 113th Proms season began on 18 July and included performances by Nigel Kennedy and Sir Simon Rattle conducting the Berlin Philharmonic Orchestra.
A Doctor Who prom was also staged, one of 164 events held in all.
