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

1. The undercroft, Fountains Abbey

This huge space is widely regarded as one of the finest pieces of medieval vaulting in Britain.

Also called the cellarium, it lay beneath the dormitory for lay brothers and it was used as a storage area.

Nowadays, it provides a home for bats and is sometimes used as a venue for concerts. In 2017, it also doubled as the cellars of the Houses of Parliament in the film Gunpowder, which told the story of Guy Fawkes' 1605 plot to kill the king.

2. Yorke's Folly, Nidderdale

Also known as the Two Stoops, Yorke's Folly was built in the 19th century by the Yorke family of Bewerley Hall, to provide work for local labourers during a period of economic hardship.

As a folly, it serves no purpose, and although it looks like the ruins of something bigger, there never was a larger structure here. That said, there did use to be a third pillar, but one was blown down in a storm in 1893.

Today, it is grade II listed and, towering above the village of Bewerley near Pateley Bridge, it serves as a landmark for walkers and a reminder of the paternalistic largesse of the gentry of a bygone age.

3. The mural on the side of The Silver Fox, 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 The Silver Fox café, whose wall it is.

4. The Chapel of Our Lady of the Crag, Knaresborough

This unique little chapel was carved out of the rock face of a quarry in the early 1400s as a shrine to the Virgin Mary on the old pilgrim's route to Knaresborough Priory.

Now a grade I listed building, it is open to the public between 2pm and 4pm on Sundays between Easter and late September. So if you want to go and pay a visit, you'd better be quick before it closes for the winter!
