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

1. Phone box mural, Knaresborough

This incredibly realistic painting stands at the crossroads where King James Road meets Aspin Lane, Crag Lane, and Stockdale Walk.

It was painted in 2021 by local artist Shirley Vine, who was commissioned by Matt and Lynn Curl, the couple who lived in the house behind the hedge.

There used to be a real red phone box on this spot, and the Curls had long described their address to visitors as "the one behind the phone box". So when BT removed the phone box, they decided to do something about it, hiring local builder Neil Watts to build a frame, and Shirley to work her trompe l'oeil magic.

2. Water trough, Ramsgill

Variously described as a water trough and a drinking fountain, this striking structure stands on Ramsgill's village green, in front of the Yorke Arms.

The structure appears to be topped with a couple of sections of column from a church. Where exactly they come from, we haven't been able to find out, but Ramsgill itself was founded in the Middle Ages as the principal grange of Byland Abbey, so perhaps that provides a clue.

3. Challenger tank, Harrogate

This intimidating vehicle is the first thing young recruits see when they first arrive at the Army Foundation College on Penny Pot Lane.

The college accepts over 900 16- and 17-year-olds each year, who train for six or 12 months there, depending on which corps or regiment they plan to join. Many receive basic, phase-one training before going to other places, such as Catterick, for trade-specific training.

4. How Hill Tower, Studley Royal

The 300-year-old How Hill Tower is a folly built in the early 18th century by John Aislabie, the owner of Fountains Abbey who created the Studley Royal water gardens.

It was built on the site of the 13th-century Chapel of Saint Michael de Monte, and it has since been used as a farmhouse, cottages and, during the Second World War, a Home Guard observation post.

Now grade II* listed, it has been in a state of disrepair for some time, but its owner, the National Trust, last year gained planning permission to carry out a major programme of repair and restoration.
