Thousands are marching through Merthyr Tydfil in Wales' third demonstration for Welsh independence.
It comes after similar marches in Cardiff and Caernarfon earlier this year.
The first march in Cardiff in May attracted crowds of over 3,000, while the event in Caernarfon saw 10,000 - double the town's population.
ITV Wales Correspondent, Dean Thomas-Welch estimated more than 3,000 people joined the march in Merthyr on Saturday afternoon.
Organisers, All Under One Banner Cymru (AUOBC) said it's important that Wales ''voice is heard.''
Sports and arts personalities, such as Neville Southall and Kizzy Crawford, will join campaigners at Penderyn Square where the rally ends.
Former Wales rugby captain and commentator Eddie Butler said he had been ''waiting for this moment.''
AUOBCymru is a Welsh grassroots movement calling for independence for Wales. It is supported by a number of groups who share the aim of securing an independent Wales, and is not aligned with or affiliated with any political party.
