Thousands of girls have descended on Dublin Zoo to celebrate 100 years of the Brownies.

The organisation, which gives girls the opportunity to build their confidence and skills, was first introduced in Ireland in 1914.

It was set up after the younger sisters of Girl Guides felt left out and said they wanted to join in.

The first branch meeting was held in Newbridge, Co Kildare, and now there are over 4,000 Brownies in Ireland. 

Olympic medalist Sonia O'Sullivan is among one of the most famous Brownies in Ireland. 

Other former Brownies include the actress Emma Thompson and the author JK Rowling. 

There are Brownies in over 100 countries around the world.
