Portinscale is a village in Cumbria, England. It is situated close to the western shore of Derwentwater and within the Lake District National Park. It is some 1.5 miles (2.4 km) by road from Keswick. For administrative purposes, Portinscale lies within the civil parish of Above Derwent, the district of Allerdale, and the county of Cumbria. It is within the Copeland constituency of the United Kingdom Parliament, and the North West England constituency of the European Parliament. The village covers approximately 0.15 square miles (0.39 km2). At the 2011 census the population totalled 560.
The name of the village means "the harlot's hut", deriving from the Old English "portcwene" (harlot) and Old Norse "skáli" (hut). The scholar Eilert Ekwall cites an undated early spelling of the name as "Portquenscale".
The antiquary W G Collingwood, commenting on an archaeological find at Portinscale, wrote that it showed that "Stone Age man was fairly at home in the Lake District". The remains of the workshop of a prehistoric tool-maker were discovered in 1901 by workmen digging out a fish-pond near the village, about 150 yards (140 m) from the north-west shore of Derwentwater. A later find was a mould dating from about 1400, used to make crucifixes for the use of religious pilgrims. Hardwicke Rawnsley, co-founder of the National Trust and vicar of Portinscale's parish church, Crosthwaite, theorised that the mouldings were sold to people en route to St Herbert's Island from Nichol End, Portinscale's embarkation point on Derwentwater. From medieval times until the 20th century, according to records at Carlisle Castle, a Court leet met periodically and appointed constables for Portinscale. In the 17th century the village was a centre of Quakerism, and for preaching without a licence several local Quakers suffered the prescribed penalty, "ye Spoiling of their goods and imprisonment of their bodys."
The main road from Keswick to Cockermouth ran through Portinscale until a bypass was built in the 1960s. In 1911 there was controversy about the county council's proposal to demolish the medieval bridge carrying the road across the River Derwent and replace it with a modern structure. There had been a stone bridge on the site since c. 1210–16, although the date of the structure under threat in 1911 is unknown. The bridge, properly called "the Long Bridge", was unusual in having two arches; on the great coach road from Kendal to Cockermouth all but two of the other bridges crossed their rivers in a single span.
Rawnsley and Sir Robert Hunter of the National Trust led the opposition to the council's proposal. They were supported by The Times, The Manchester Guardian and the Royal Automobile Club, and the proposal was dropped. The old bridge survived for another 43 years, until it was damaged beyond repair by floods in December 1954. A temporary metal girder Callender-Hamilton bridge was placed across the river, to carry alternating one-way traffic, and a new permanent bridge was built 400 yards (370 m) downstream, allowing the diversion of the main road to by-pass the village. After the new road bridge was opened, the temporary metal structure was replaced by a new pedestrian bridge on the old site, allowing foot traffic between Portinscale and Keswick on the path across the fields known as the Howrahs.
The village hall was opened on 10 October 1925. The village has one pub, the Farmer's Arms; a restaurant, the Chalet; a café, the Dandelion; the Derwent Water Marina; numerous bed-and-breakfast establishments; and a substantial and long-established hotel, the Derwentwater, originally called the Black Dog, and then from about 1815 the Marshal Blücher. In 1847 the authors of a guide to Cumberland wrote, "The Blücher hotel occupies a delightful situation in the village … attached to it are neat public gardens, or pleasure grounds, and there is an interesting aviary, in which, amongst several other valuable birds are two golden eagles, – perhaps the only birds of the kind in the north of England."
Next to the hotel is Derwent Hill Outdoor Education and Training Centre. This has been owned by Sunderland City Council since 1962. It is a residential centre offering courses for children and young people, leadership and management training, conference facilities and group accommodation.
On the edge of Portinscale is Derwent Bank, a large house built as "Finkle Street House" in 1785; since 1937 it has been a centre for walking holidays. Just outside the village are two large country houses designed by Alfred Waterhouse, Fawe Park, built in 1858, and Lingholm, built in the 1870s. The former is close to the Nichol End stop of the Keswick Launch Company's Derwentwater ferry service.
