Thousands of women are gathering to turn British cities into rivers of green, white and violet to mark 100 years since the first U.K. women won the right to vote.

Part artwork, part parade, the "Processions" will see women march through London, Edinburgh, Cardiff and Belfast clad in the colors of the suffragette movement that fought for women's right to vote. Participants will carry home-made banners, inspired by suffragette slogans, reflecting the lives of British women today.

The London march will weave through the heart of British capital on Sunday, passing Piccadilly and Trafalgar Square and ending at Parliament.

In 1918, the Representation of the People Act granted property-owning British women over 30 the right to vote. It would be another decade before other British women won the same voting rights as men.
