🌸November 5th Lighting Up Pink - Project Pink Initiative🌸

Last night we lit up the polestar roundabout in pink as part of the project pink initiative, showing solidarity and support for women and girls affected by gender based violence.

This campaign aims to end violence against women & girls and to create a safe , welcoming environment for everyone to socialise, exercise and enjoy the outdoors.

Buildings across Ireland were glowing pink to raise awareness and stand united against violence.
