History of Diadema

Until the 1940s, Diadema was constituted by four neighbourhoods belonging to São Bernardo do Campo: Piraporinha, Eldorado, Taboão e Vila Conceição. Dispersed, they were only connected through roads of difficult passage and each neighbourhood had its own life. Piraporinha near São Bernardo; Taboão, also connected to São Bernardo do Campo due to the proximity and to São Paulo through Água Funda Avenue. Eldorado, a neighbourhood that had unique characteristics, because of the Billings Reservoir, had a greater proximity to São Paulo, to the Santo Amaro region and finally Vila Conceição formed by the farms that once belonged to the Vila Conceição Company
