A crown ... I'm just playing with the functionality of this!

Pointy hats were worn by clergy

@gsenior1968  you can note the difference in resolution by looking at the words "tower hill" in both this map of london and the one next...this map has much worse resolution.

This is a meander in the middle or lower course of a river

The water flows fastest around the outside of the bend and erosion takes place here. A river cliff is formed. If you could slice through the meander from one side to the other, this is what you would see:

This river is flowing across a wide flood plain which it has formed by repeatedly depositing sediment on the valley floor during times of flood. @tomadmin 

The ripples in the water are indicative of helicoidal flow; the water 'spins around' in the river as well as making its way to the sea. @tomadmin 

The Romans built Hadrian's Wall in the early part of the second century to mark the northern limit of their empire.

A national trail now runs the entire length of the wall, although only small sections of it remain intact. @tomadmin

One of the best preserved parts of the wall is the fort at Vindolanda near Hexham @tomadmin @gsenior1968 

Sections of the wall run along the top of a steep escarpment where man and nature combined to protect the Roman Empire from the Picts who lived beyond its borders.
