Hours after flying on a rickety 19-seater propeller plane and landing on a dirt strip, you get to the village of San Buenaventura in the heart of the Bolivian Amazon.

Here, in a simple one-storey brick house next to a row of wooden shacks, is the home of Antonio Garcia Baron.

He is the only survivor still alive of the anarchist Durruti column which held Francoist forces at bay in Madrid during the Spanish Civil War (1936-1939) and the founder of an anarchist community in the heart of the jungle.

Mr Baron, 87, was wearing a hat and heavy dark glasses. He later explained that they were to protect his eyes, which were damaged when he drank a cup of coffee containing poison nine years ago.

It was, he said, the last of more than 100 attempts on his life, which began in Paris, where he moved in 1945 after five years in the Mauthausen Nazi concentration camp, and continued in Bolivia, his home since the early 1950s.
