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.

Modern

The Modern Period, about 1915 AD to the present (the 20th and 21st centuries AD)
In recent years archaeologists have realised the importance of recording modern sites. They do this so that in the future people will be able to look at the remains to help them understand the events to which they are related. more ->

Roman
|
About 43 AD to 409 AD (the 1st century AD to the 5th century AD)
The Roman period comes after the Iron Age and before the Saxon period.
The Roman period in Britain began in 43 AD when a Roman commander called Aulus Plautius invaded the south coast, near Kent. There were a series of skirmishes with the native Britons, who were defeated. In the months that followed, more Roman troops arrived and slowly moved westwards and northwards. 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 ->
