Portreath (Cornish: Porthtreth or Porth Treth)[2] is a civil parish, village and fishing port on the north coast of Cornwall, England, United Kingdom.

Devon contractor Samuel Nott was engaged to build the first mole (or quay) in 1713 on the western side of the beach, near Amy's Point.

[10] With the population growing, a church was built in 1827; the Portreath Hotel (1856), Methodist Chapel (1858), Basset Arms (1878) and the School (1880) all followed.

[9] The Portreath Tramroad, the first railway in Cornwall, was started in 1809 to link the harbour with the copper mines at Scorrier and St Day.

It was horse-drawn with wagons on an approximately 4 ft (1.2 m) gauge using L-shaped cast iron plates on square granite blocks.

[17][18] Nance Wood, 1 mile (1.6 km) to the south east of the village, is a narrow strip of semi-natural woodland on a steep north-facing slope which was designated as a Site of Special Scientific Interest for its biological characteristics.

Most of the woodland is a 4–6 metres (13–20 ft) high, wind-pruned, sessile oak (Quercus petraea) last coppiced in the first half of the 20th century.

The woods are one of only two sites in Britain to contain Irish spurge (Euphorbia hyberna), which is listed in the Red Data Book of rare and endangered plant species.
