Acclaimed sculptor and Nottingham native James Arthur Woodford was commissioned to craft a group of sculptures depicting the legendary characters of Robin Hood and his Merry Men, to commemorate the visit of the then Princess Elizabeth and the Duke of Edinburgh in 1949.

In the early 20th Century, the south pier at Newlyn was extended to give better protection to the harbour and a tidal observatory was built at its north end. The observatory was one of three constructed at the request of Ordnance Survey to establish Mean Sea Level.

With the observatory being completed in 1914, hourly measurements were taken of the height of the tide between 1915 and 1921, determining that Newlyn was the most stable and therefore the principal place to establish Mean Sea Level for the entire country.

The former lifeboat house, built in 1884, was designed by CH Cooke and represents the crucial role played by the Royal National Lifeboat Institution (RNLI) in saving lives at sea since the 19th Century.

Historic England said its wide gabled structure and ornamental treatment, made up of fish-scale tiling, decorative moulded brick, and a beautifully incorporated bay window, created a finely detailed and strikingly composed building.

The University of York Campus designed landscape was laid out between 1963 and 1980.

Historic England described it as a high-quality post-war university landscape that fulfils the architects' masterplan vision of creating a town in miniature with a pedestrianised environment. The landscape is relatively unaltered since it was laid out.

The building is largely intact and features many surviving fixtures dating back to the mid-20th Century, including an engine-testing control panel, observation windows, wing spar mount assembly, roller doors, pierced metal sheet lining, as well as fittings and support for a de-tuner.

Cattle trough and drinking fountain, Hampstead, London

Image copyright Historic England Image caption Cattle Trough and Drinking Fountain, Spaniards Road, Hampstead, London is listed at Grade II in 2018

Cattle troughs were once commonplace in Britain, with the Metropolitan Drinking Fountain and Cattle Trough Association responsible for more than 1,000 of them.

About 500 of these were located in London, however a large number have now been lost. The trough in Spaniards Road is believed to have been erected in 1916, making it a particularly late example of its type. Although the pump and spout mechanism are missing, the cattle trough serves as a reminder of a time in the early 20th Century when horse-drawn transport was still commonplace, despite the increasing use of cars.
