The Siegel modular varieties are the higher dimensional analogue of the modular curve: they parameterize abelian varieties of a given dimension. Equipped with a certain level structure, cohomological considerations allows one to construct an "etale local model" - a space with the same etale local structure which is easier to work with. We will describe the construction of local models, some of the geometry within, and a few applications of this structure.
