In 1874, control of the Fiji Islands was ceded to the United Kingdom. In 1877, the colonial authorities decided to move the capital to Suva from Levuka, Ovalau, Lomaiviti, because Levuka's location between a steep mountain and the sea made any expansion of the town impractical. Colonel F.E. Pratt of the Royal Engineers was appointed Surveyor-General in 1875 and designed the new capital in Suva, assisted by W. Stephens and Colonel R.W. Stewart. The transfer to Suva was made official in 1882.
