So, it's been quite a day for Hadrian's Wall of Sound.

Starting in Bowness-on-Solway and travelling the 73 mile length of the wall, the event has brought together hundreds of people and communities.

As part of BBC Music Day, we've had unicyclists, opera singers, harpists and amateur bands. You can catch up on all the best photos from the day here.

It has been an amazing experience. From all of us at the BBC in the North East and Cumbria, thank you for taking part and sharing in it.

Our Hadrian's Wall of Sound senior producer Helen Amess says: "I am incredibly proud of everyone who took part today. We did Hadrian's Wall proud. It's been an amazing experience."

Here are some of the performers.

Helen said: "I know it sounds a bit naff, but this was one of the best experiences of my life. From 13 hours ago back in Bowness-on-Solway, to meet all these people who are making music along Hadrian's Wall for fun, was just brilliant."

Just below the Tyne Bridge, the choristers handed over the baton to Circus Central performers who then made their way along the quayside on unicycles.

Another memorable sight.
