Introduction & nbsp; The Big Battery was established in 1617 and completed in 1626, named the Saint Paul Battery, which is commonly referred to as the "Big Battery" by Macau residents. In the nearly four hundred years of history, the internal buildings of the Great Battery have been renovated multiple times. The gate of the large battery faces south, and in the early days, the entrance was a gunpowder storage warehouse; In the center of the upper level is a three story tower (now defunct), each level equipped with artillery; There are also four rows of houses next to it, which are barracks for Australian governors and officers and soldiers. There are steps on both sides of the dormitory connected to the entrance of the lower level. The battery is equipped with a water tank and a military supply warehouse, with sufficient reserves to cope with a siege lasting for two years. In summary, this battery was the core of Macau's defense system at that time, forming a wide artillery defense network covering the east and west coasts. From 1623 to 1740, this place served as the residence of the city defense commander and the governor of Australia. The Big Battery has always been a military restricted area until 1965 when the original barracks were rebuilt into a meteorological station. After the meteorological station moved in 1966, it was opened as a tourist area
