Roberts International Airport — Monrovia, Liberia

Built by United States military engineers during the Second World War, ROB began life as Roberts Field, a strategic airbase supporting Allied operations across the South Atlantic and into North Africa. The airport sits roughly 35 miles southeast of Monrovia, Liberia's capital, near the town of Harbel and the vast rubber plantations that Firestone established in the region decades earlier. It takes its name from Joseph Jenkins Roberts, a Virginia-born settler who became Liberia's first president after the country declared independence in 1847. ROB remains the country's main international gateway, though its distance from the capital has long posed logistical challenges for travelers. The airport suffered heavily during Liberia's civil wars in the 1990s and 2000s, with runway damage and periods of near-total closure, before international assistance helped fund its rehabilitation. Today it handles a modest but steadily recovering schedule of flights connecting Liberia with West Africa, Europe, and beyond.
