Dr Helen Pankhurst, great-granddaughter of suffragette Emmeline - and her 20-year-old daughter Laura - led a mass walk along Bankside and the South Bank on Sunday to mark International Women's Day.
The 'Walk In Her Shoes' event – organised by the Care International charity – began at The Scoop at More London and ended at Southbank Centre's Women of the World festival.
At The Scoop amphitheatre BBC Radio 4 Women's Hour presenter Jane Garvey chaired a panel discussion featuring musician Annie Lennox, DJ Gemma Cairney, comedian Bridget Christie and Everyday Sexism project founder Laura Bates.
Helen Pankhurst said: "We're raising awareness and taking action against one of the unnecessary gendered shackles blighting the lives of women and girls around the world – the gruelling chore of water collection, which in 2015 simply should not be holding girls back from education, and women from paid work."
She added: We are coming together in solidarity to celebrate progress made on women's rights and to galvanize for the road ahead.
"We do so in the time honoured tradition of a march, walking shoulder to shoulder, as a visible manifestation of a global conscience."
International development secretary Justine Greening also addressed the gathering at The Scoop.
