Beira is the fourth largest city in Mozambique. It lies in the central region of the country in Sofala Province, where the Pungwe River meets the Indian Ocean. Beira had a population of 397,368 in 1997, which grew to 533,825 in 2017. It holds the regionally significant Port of Beira which acts as a gateway for both the central interior portion of the country as well as the land-locked nations of Zimbabwe, Zambia and Malawi.
