The Batavia Region is located in the Netherlands. The land in the region is incredibly fertile due to it's river delta formed by the waters of the Rhine and Meuse rivers. 

Historically, the region was very important for the Roman empire as a source of soilders. During the renassaince, the Dutch became enfactuated with the lost culture of the region. As a result, they sought to capture the feeling of Batavi culture throughout this time, leading them to name several colonies after the region.

In "Eighteen Hundred and Eleven, a Poem", the dykes of Batavia are referred to. This is a refrence to the sea walls built in Batavia to prevent flooding. The region is prone to flooding due to its proximity to both the sea and the rivers.
