The city centre was planned to be functionalist, with major buildings designed and built in the style of Modern architecture. The city is surrounded by smaller buildings. The city's central business district (CBD) is still under construction so when one says "downtown", they actually mean the "Main Mall" and "Government Enclave" areas where tall buildings are usually found. The Main Mall, a car-free shopping and commercial area, runs in an east–west direction with the Government Enclave and National Assembly on the west end and the Gaborone City Town Council complex on the east.
