Flowers and notes have been left in the village of Garreg, in Gwynedd, near the scene.

Wilf Fitchett, Jevon Hirst, Harvey Owen and Hugo Morris, from Shrewsbury, were found nearby in an overturned, partially submerged car.

"May god keep you in his care. Sending love and strength to all family and friends," read one note.

Candles have been lit in memory of the four teens at Shrewsbury Abbey, where friends Alfie and James visited.

"It's just a horrible feeling... knowing some lads I was so close to - seeing almost every single day - I'll never see again," said James.

Alfie added: "They were just lovely, lovely people, it doesn't feel that they won't be here anymore."

In Shrewsbury Abbey, a steady stream of students have been arriving to leave flowers and light candles.

Shropshire council has held a silence to remember Jevon, Harvey, Wilf and Hugo.

"I want to express my deepest sympathies to the friends and families of the four teenagers from Shrewsbury who were found dead yesterday in north Wales," said council leader Lezley Picton.

“I would also like to thank the emergency services for their work in such difficult circumstances, not just in north Wales but those who had to deliver the heart-breaking news.

“I ask that we pause for a minute to remember Jevon, Harvey, Wilf and Hugo, and allow those close to them the privacy to grieve in peace.”

The farmer who owns the land the boys were found on said he wished he could have found them and been able to help.

"The car was about 30m from our house. I saw it in the ditch. It was upside down, very close to the road," said Rhys Williams, who lives near Llanfrothen.

"It’s a tragic loss of young lives. We just wish we’d have heard something and that we could’ve helped them.

"Our hearts absolutely go out to the four families and all the friends of the young lads.”

They didn't know them, but the community near where the boys died has felt the loss deeply, according to BBC Wales' Nick Servini.

A service was held on Wednesday at the cenotaph in Llanfrothen, Gwynedd.

"One woman said even though she didn't know them she hasn't been able to stop crying since," he added.

Charley Williams runs grief cafe, external sessions in Shrewsbury.

After one at the town's library next Monday, she plans to move to the bandstand at Shrewsbury's main park, The Quarry, for a gathering there.

Ms Williams told BBC Radio Shropshire it was for "anyone who wants to come and either have their voices heard, or just gather with people that are all experiencing the same grief and loss".

“As a community, to show up for one another, to show up for the families if you’re a close member of their community – that feels really important," she said.

"It’s a huge shock for the community and it’s going to take time.”

One of the businesses closed in Shrewsbury as a mark of respect is pizza restaurant Dough & Oil, where Harvey worked.

"Harvey, our boy," the restaurant wrote on its Instagram page, alongside a picture of him in his work uniform, a bowl of pasta in his hand, taken just two weeks ago.

"Our love, thoughts and condolences go out to Harvey’s family and to those of his friends, their lives full of promise cut so tragically short," it read."Harvey you’ll be forever in our hearts."

Shrewsbury is in mourning following the teens' deaths, with people in the town telling the BBC it would be a long time before they would make sense of the tragedy.

The stage was set in Market Square for the Christmas lights switch-on, an event that draws thousands for music, merriment and a night of festive shopping.

Instead, the only crowds gathering in Shrewsbury are those of students - solemn and silent, consumed with shock and grief over the deaths of their friends.

The switch-on is cancelled, the start of late-night shopping delayed for a week. Celebrating Christmas is the last thing on anyone's mind here.

An underwater search team has arrived at the scene where the car was found upside down, partially submerged in water.

The bodies of four teenagers were found after it appeared to have left the road near Tremadog, Gwynedd.

Penny Crook attended the service held for the boys in Llanfrothen and says she thinks the entire community of north Wales is saddened.

"My husband organised the photographs that are there. It brings to young people the reality of how fragile life is.

"No-one was to know and no-one knows what's ahead, so I guess we end up giving joy and thanks for each day we have."

The Archbishop of Wales sends a message of condolence to the families of the dead teenagers.

Andrew John says: "I wish to express my deep sadness at the tragic death of the four teenage boys found dead in their car in north Wales.

"It is heartbreaking that the lives of these four young boys have been so tragically cut short.

"My thoughts and prayers are with the families and friends of Jevon, Harvey, Wilf and Hugo.“

Reverend Kim Williams, who is the minister in the area where the bodies were found, says churches in the area are open for quiet reflection and prayer, and also welcomed people to light a candle for the boys and pray for their families, friends and all who will miss them.

Candles are being lit in windows in Shropshire as a tribute to Jevon, Harvey, Wilf and Hugo, from Shrewsbury.

Churches across town will be open for prayers and quiet reflection.

People in the hometown of the four teenage friends killed in the crash say it will be a long time before they can make sense of the tragedy.

Market Square was set for the Christmas lights switch-on, which is now cancelled.

Instead, the only crowds gathering in Shrewsbury are those of students, consumed with shock and grief over the death of their friends.

Margery, who lives near the crash site, went to the service held in Llanfrothen and says: "I cried last night because I thought that could be my grandchildren who had gone out just for the weekend for a lovely time and it ended so tragically.

"Our church we will be praying for the family on Sunday. God will give them peace in this terrible situation."

It says:

"Dear parents and carers.

"It is with great sadness that we write to you about the tragic death of four Shrewsbury college students.

"Our thoughts, love and prayers are with all the families and their friends at this incredibly difficult and sad time. As two schools, knowing one of the boys as a formal pupil of ours, this has affected our schools and our community greatly.
