A group of 25 pupils and staff from Monkton Priory CP School and the Priory Project recently visited the European Parliament in Brussels.
The Priory Project based at the school provides educational support for secondary school-aged gypsy children.
With the support of Save The Children and the Welsh Assembly Government (WAG), they recently made a DVD about their views and experiences which they showed to a group of MEPs.
The party - led by project leader Bev Stephens and headmaster William Rees - were hosted for their visit by Wales MEP Jill Evans who spoke to the group in the Parliament building.
They were also addressed by Belgian MEP Els de Groen, who has a great interest in Roma matters and by Hungarian MEP Livia Jaroka, herself a Romany gypsy.
Presentations were also made by Carol Mooney from the Social Inclusion department of WAG; Ant Edwards of Save The Children and by Kirby Jones, a Priory Project pupil who spoke to the MEPs about the work being done in Pembrokeshire.
The group also attended a plenary session in the main chamber of the European Parliament.
Said Jill Evans: "I have learned a lot from meeting these young people, they were impressive advocates for the gypsy/traveller community and presented first hand evidence of their experiences and the challenges they face."
