The Guides were joined by 1st Louth Rangers on a journey visiting each of the nine decades.
Each decade was represented with the Guides, Rangers and Leaders presenting a display about their particular decade, showing what took place including fashion, music, Guiding, current affairs and inventions.
Everyone was dressed up in their respective fashion, and each group demonstrated a game or quiz originating from their decade.
A birthday party would not be complete without food, so everyone was invited to munch on food which represented each of the nine decades.
The girls were presented with a lovely badge, which they helped design, to commemorate the special occasion.
A 7th Louth Guides spokesman said: “The cake in the photograph was very kindly made by the mother of a young Leader, following the design on the ‘birthday badge’.
“The 7th Louth Guides are looking forward to seeing what the next ten years will bring!”
