Botswana's tallest building is the landmark home of the Gaborone iTowers business centre. The mixed-use building occupied by the business centre is one of three towers to dominate the city skyline from the new central business district in the heart of Botswana's capital. The building, which is built to the highest ‘green' and technical specifications, is situated close to the High Court and Court of Appeal. Many law firms are located in the district, which is experiencing a boom in construction and development. The city, with its educated labour force and good infrastructure, has seen rapid growth and as Botswana's economic core has attracted many corporate HQs. It's also the location for the Botswana Stock Exchange and government departments. Sir Seretse Khama International Airport and five major roads serve the city, which offers great access to other African markets. The biggest industries are mining, tourism and cattle.
