Tranqueira was the most important suburb of Malacca. The suburb was rectangular in shape, with a northern walled boundary, the straits of Malacca to the south and the river of Malacca ("Rio de Malaca") and the "fortaleza's" wall to the east. It was the main residential quarters of the city. However, in war, the residents of the quarters would be evacuated to the fortress. Tranqueira was divided into a further two parishes, São Tomé and São Estêvão. The parish of S.Tomé was called Campon Chelim (). It was described that this area was populated by the Chelis of Choromandel. The other suburb of São Estêvão was also called Campon China ("").
