The Orange Order was founded back in 1795
Three of this year's Twelfth demonstrations have been selected by the Grand Orange Lodge of Ireland for tourist flagship status.
The Twelfths in Enniskillen, Carrickfergus and Ballynahinch have been chosen to get extra support during the run up to the festival.
Grand Orange Lodge Director of Services, Dr. David Hume said: "This is an Olympic year and the centenary year of the Ulster Covenant as well as the Queen's Diamond Jubilee, so it will be a memorable year generally and we wish Carrickfergus, Ballynahinch and Enniskillen districts every success in their plans."
Tourism Minister Arlene Foster said: "The Grand Orange Lodge of Ireland's announcement that it has selected Twelfth demonstrations in Enniskillen, Carrickfergus and Ballynahinch as flagship events is welcome news.
"The Flagship concept focuses on those parades that want to broaden their appeal to attract a tourism audience and I have no doubt that those involved in the three selected demonstrations will provide a varied and vibrant programme of events.
"I look forward to attending the Flagship Parade in Enniskillen and wish the Grand Orange Lodge of Ireland every success with its preparations for the Twelfth."
The Order also confirmed it will be training Orange Welcome Hosts who "will act as ambassadors for the Orange Institution and its traditions on the Twelfth itself."
The annual celebration in Rossnowlagh in County Donegal was held on Saturday.
