Administrative building — this category includes public or private facilities related to the city's infrastructure, with the exception of entertainment venues. For example, we have added objects such as water towers, which are now merely architectural monuments.

You will also find the largest markets in Vietnam in this subgroup. For example, the central markets of the city of Hoi An, Con Dao Island, the metropolis of Ho Chi Minh City, and the city of Lang Son. Interestingly, some of these markets may be older than the official establishment of the city itself.

Various factories and plants can also be found in this subgroup. We have added information about fish sauce factories in Phan Thiet and the ceramic factory in Ha Long. There is data here about the pearl farm on Phu Quoc Island. This category includes assembly halls, committees, palaces, departments, as well as the Bitexco Financial Tower.
