Administrative Management and Defensive Measures

Following the Portuguese arrival in Macao in the 16th Century, the sparsely populated peninsula nurtured many business activities and gradually grew into a major trading port serving China and the West. European powers then coveted the city of Macao. In the early 17th Century, the Portuguese started to build fortresses and solid defences along Macao's coastal area and strategic locations with the implicit consent of the Ming and Qing governments via the policy of 'controlling foreigners by foreigners'.

To increase Macao's defensive power, the Portuguese built a cannon foundry near the Fortaleza de Nossa Senhora do Bom Parto in Praia Grande, which supplied military defence equipment such as cannons to the local market in addition to exporting to China, Japan, Southeast Asia and Europe.
