Ten young people from across Cardiff have been invited to the Microsoft Centre in London.
The group, aged 13-17, have been involved in developing the online services for Cardiff Youth Services and have taken part in coding and programming workshops arranged by the Cardiff Commitment.
During the experience the group learnt more about coding, Minecraft and the type of jobs within the industry. They also visited iconic London landmarks such as Buckingham Palace and Big Ben.
For many of the group, this was the first time they had visited London and for one it was the first time they had ever left Cardiff.
