Here are the answers to this week's Sunday Picture Quiz. How well did you do?

1. The Harrogate 1571 sculpture

This steel sculpture, near the bandstand in Harrogate's Valley Gardens, commemorates the 1571 discovery by William Slingsby of the unique medicinal properties of the mineral spring water at Tewit Well, which led to Harrogate becoming internationally renowned as "The English Spa".

Harrogate 1571 was created in 2019 by Eddie Roberts of Cult-Ore and illuminated by Yorkshire lighting expert James Bawn (pictured), of Element 3 Design.

Sharp-eyed observers quickly spotted a mistake before it was even unveiled – among the spa-related words cut out of the steel, the word 'sulphur' is misspelled 'sulpher'. A corrected version was reported at the time to be in the works, but for reasons unknown it never materialised, so the misspelling remains. It still looks great though.

2. Toft Gate Lime Kiln, Greenhow Hill

This unusually intact piece of Nidderdale’s industrial heritage lies near the top of Greenhow Hill, above Pateley Bridge.

It was built in the 1860s to produce quicklime for use in agriculture and construction. Limestone quarried from the hill was heated by fires in the kiln, and the noxious smoke billowed out of the flue stack some distance away (near the present-day carpark).

It was used throughout the later 19th century, but the industry developed larger works, eclipsing and ultimately outperforming small ventures like this one.

3. The mural on the side of Hoxton North, Harrogate

It's unclear how old this mural is, but it has adorned the end wall of the Royal Parade terrace of shops for at least a couple of decades, and so will be a familiar sight for anyone who passes this way regularly.

For a long time, it only showed the Queen – the then Prince Charles (now King Charles, of course) was only added later.

The wording in the speech bubble has also changed several times over the years, and now refers to one of the most popular pastimes at Hoxton North café, whose wall it is.

4. Fisher's Hall folly, Hackfall

This is one of five follies in the woods at Hackfall, which lies just outside the pretty village of Grewelthorpe, between Ripon and Masham.

The follies were created by William Aislabie, who is better known for having created the water gardens at Fountains Abbey. Hackfall had been bought for £906 in 1731 by William's father, John Aislabie, who also started the work at Fountains Abbey. As well as follies, William created grottoes, waterfalls, a fountain and surprise views.

In 2007, the Grade I listed gardens, which actually feel more like wild woodland, were restored thanks to a £1 million grant from the Heritage Lottery Fund. This has helped to preserve the buildings, restore water features, improve the footpaths and open up the vistas.
