The historical maps record the geographical features of the Macao region from the 18th century to the beginning of the 21th century. Through the surveying information on the maps, they reflect the development and changes of the Macao region over the years. From the early small-scale historical maps which depict the geographical location of the Macao region in the Pearl River Delta, to the large-scale historical maps that display basic information on the then physical and human geography of the Macao region, such as topography, community development and distribution of human settlements, they have important reference value for learning about the changing times, history, culture and geographical environment of the Macao region. |
