Luanda is the capital of Angola. It is on the Angola's Atlantic coast. Its current renaissance is a truly inspiring success story. In recent history, the center of decades of conflict, the start of the 21st century has seen a massive boom in construction in Luanda, where peace and stability have attracted numerous foreign companies to invest in offices in the city. The government of Angola, getting rich off revenue from oil, diamond, and other natural resources, is also investing heavily in and around Luanda, including large social housing highrises to replace slums and existing dilapidated (and often bullet-ridden) highrises; extensive repaving; the construction of several six-lane highways leading out of the city; the reconstruction of railroad lines leading out of the city; and a large new airport on the south side set to open in 2011.
