Earthwork
|
Earthworks can take the form of banks, ditches and mounds. They are usually created for a specific purpose. A bank, for example, might be the remains of a boundary between two or more fields. Some earthworks may be all that remains of a collapsed building, for example, the grassed-over remains of building foundations.
In the winter, when the sun is lower in the sky than during the other seasons, earthworks have larger shadows. From the air, archaeologists are able to see the patterns of the earthworks more easily. Earthworks can sometimes be confusing when viewed at ground level, but from above, the general plan is much clearer.
Archaeologists often carry out an aerial survey or an earthwork survey to help them understand the lumps and bumps they can see on the ground.

Aerial Photograph
|
Aerial photographs are taken during an aerial survey, which involves looking at the ground from above. It is usually easier to see cropmarks and earthworks when they are viewed from above. Aerial photographs help archaeologists to record what they see and to identify new sites. There are two kinds of aerial photographs; oblique and vertical.

Iron Age
|
About 800 BC to 43 AD
The Iron Age comes after the Bronze Age and before the Roman period. It is a time when people developed the skills and knowledge to work and use iron, hence the name ‘Iron Age’ which is given to this period. Iron is a much tougher and more durable metal than bronze but it also requires more skill to make objects from it. People continued to use bronze during this period. more ->
