BBC News - Search for Spanish Civil War archaeology dig volunteers
A Ceredigion archaeologist is looking for volunteers to join a new International Brigade to work on a dig at a Spanish Civil War battlefield.
Salvatore Garfi, from Pontrhydygroes, set up the International Brigades Archaeology Project (IBAP) earlier this year.
He aims to take a team to Spain later this year to study the archaeological remains of the war.
About 30 volunteers have so far expressed an interest.
Mr Garfi will work with Spanish archaeologists and volunteers from different countries at the town of Belchite in north east Spain in September.
