Port Frederick is the second largest and oldest city in Guelphia. As of 2013, Port Frederick has a population of just over 190,000 people. All of the conurbation of Port Frederick is administered as part of the Albanyshire County Council. The second European settlement in Guelphia, Port Frederick was built by the Guelphia Company in 1835, and was where the country was founded on the 18 February 1836.
Port Frederick is named in honour of the late British Prince Frederick, Duke of York and Albany, (1763 – 1827), the second son of George III and his wife Charlotte of Mecklenburg-Strelitz, and the late brother of William IV, who was the British sovereign at the time Guelphia was settled in the 1830s. As well as the city, the Prince also gave his name to the county in which it was situated.
Before the European settlement of Guelphia, The indigenous Ngati Mōri were the sole inhabitants of what later would become Port Frederick. Geological and archaeological evidence has confirmed that the area was permanently inhabited, had a relativity dense population, and saw the widespread farming of kūmara (Ipomoea batatas) on the alluvial floodplains that make up much of lower Maria and Wilson valleys. The oldest finds in the area date to the early 1550s, suggesting Guelphia was settled rapidly after first contact took place in the 1540s.
Port Frederick is situated in the north-east of Brunswick Island (41°7'30"S 159°59'30"W), and lies on the eastern banks of the River Maria, about 1⁄2 mile (0.80 km) from the where the river meets the sea. As a coastal settlement, the city lies just above sea level, with the city centre having an elevation of just 18 feet (5.5 metres).
