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.

Cropmark
|
Cropmarks appear as light and dark marks in growing and ripening crops. These marks relate to differences in the soil below. For example, parched lines of grass may indicate stone walls. Crops that grow over stone features often ripen more quickly and are shorter than the surrounding crop. This is because there is less moisture in the soil where the wall lies.

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.

Medieval
|
1066 AD to 1539 AD (the 11th century AD to the 16th century AD)
The medieval period comes after the Saxon period and before the post medieval period.
The Medieval period begins in 1066 AD.
This was the year that the Normans, led by William the Conqueror (1066 – 1087), invaded England and defeated Harold Godwinson at the Battle of Hastings in East Sussex.
The Medieval period includes the first half of the Tudor period (1485 – 1603 AD), when the Tudor family reigned in England and eventually in Scotland too.
The end of the Medieval period is marked by Henry VIII’s (1509 – 1547) order for the Dissolution of the Monasteries in the years running up to 1539 AD. The whole of this period is sometimes called the Middle Ages.

Post Medieval

About 1540 AD to 1750 AD (the 16th century AD to the 18th century AD)
The Post Medieval period comes after the medieval period and before the Imperial period.
This period covers the second half of the reign of the Tudors (1485 – 1603), the reign of the Stuarts (1603 – 1702) and the beginning of the reign of the Hannoverians (1714 – 1836).
