Field Survey
|
The term ‘field survey’ is used to describe all work that does not disturb archaeological deposits below the ground through an excavation. Field survey techniques involve recording measurements that help archaeologists draw plans or diagrams of archaeological features. There are a variety of different field survey techniques, including geophysical survey, building recording survey, field walking survey, landscape survey and earthwork survey.

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.

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.
