Documentary Evidence
|
Documentary evidence is another name for written records. The first written records in Britain date back to the Roman period. Documentary evidence can take many different forms, including maps, charters, letters and written accounts.
When archaeologists are researching a site, they often start by looking at documentary evidence to see if there are clues that will help them understand what they might find. Documentary evidence can help archaeologists understand sites that are discovered during an excavation, field survey or aerial survey.

Resistivity Survey
|
A resistivity survey measures the electrical resistance of the soil and any buried features within it. Where there are buried pits and ditches, there is less resistance to the flow of electricity. Where there are archaeological remains made from stone, for example a wall, the resistance is greater. These differences in resistance are measured and recorded by archaeologists using a resistivity meter. The measurements can then be used to plot features that exist below the ground. See also geophysical 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.

excavation
|
Archaeologists excavate sites so that they can find information and recover archaeological materials before they are destroyed by erosion, construction or changes in land-use.
Depending on how complicated and widespread the archaeological deposits are, excavation can be done by hand or with heavy machinery. Archaeologists may excavate a site in a number of ways; either by open area excavation, by digging a test pit or a trial trench. more ->

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. more ->

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). more ->
