It's time to go crazy because we have some amazing news for Game of Thrones fans. The production team has started filming scenes for the Tower of Joy scene and today a videos of the fight were posted online!

The shooting is going on at Castillo de Zafra, which is being used as the Tower of Joy. The video shows Ned Stark and Ser Arthur Dayne fighting outside the Tower of Joy. People weren't allowed near the venue but that didn't stop some fans sneaking around and capturing the video of the fighting scene. Take a look at the video that has been shared by Javi Marcos.
However, that's not the only video that was posted. Here's another video that was shared by Richard Atkinson in which we are able to get a better view of the fight.
In the video we can hear Richard talking about Sean Bean fighting with an unknown person. We are sure that it's the fight between Ned Stark and Ser Arthur Dayne and in the end we can see another person who comes from the back and stabs Dayne. The person must be Howland Reed as Ned Stak has said that Howland Reed had saved his life from Ser Arthur Dayne.
