The Radio Recruits go on an adventure to Carlisle Castle, a historic building over 900 years old in the county of Cumbria. They climb the castle walls, learn all about who lived there and explore the dungeons, but what will they find?

Go Jetters: Radio Recruits introduces little listeners to famous landmarks around the United Kingdom. Guided by their disco-loving mentor, Ubercorn, our Radio Recruits explore new places and discover ‘funky facts’! #CBeebiesRadio
