HILLS, steel and a reight good accent - everyone knows what Sheffield is famous for.
But when city residents and celebrities took to Twitter to shout about them, as well as some of its lesser known attractions, the topic was so popular it became a global ‘trend’ on the site.
Using the marker #IfYouKnowSheffield, people posted about the everyday curiosities and historical traditions of Sheffield.
Former cricket star Michael Vaughan, now living in Baslow, even posted his observations on city nights out.
He typed: “#IfYouKnowSheffield... You will have had a fishcake and mushy pea buttie from the Devonshire Chippy.”
Sheffield pop artist Pete McKee also joined the trend - which was later copied by people living in other cities. He wrote: “#IfYouKnowSheffield... You are a person of impeccable taste and I love you.”
Businesses and football fans caught on to using the #IfYouKnowSheffield tag to promote their causes.
But some of the most popular topics focused on dialectal words like ‘mardy’ and former landmarks including the hole-in-the-road roundabout or Tinsley Towers.
Here are some of our favourite posts.
