This surviving segment of the city’s old defense structures that were built as early as 1569, is a remnant of an early Portuguese tradition of constructing defensive walls around the main port settlements that were part of their old maritime routes, also found in Africa and India. This remnant section of the wall measures 5.6 metres high by 18.5 metres lengthwise and is 1 metre thick. This wall also bears testimony about the incorporation of local construction techniques and materials, such as the compound that we can find here, commonly known as “chunambo”, which is a mixture of clay, soil, sand, rice straws, crushed rocks and oyster shells compacted in successive layers.
