  The purpose of this paper is to introduce a new structure `primal'. Primal is
dual to grill. Like ideal, dual of filter, this new structure also generates a
new topology named `primal topology'. We introduce a new operator using primal,
which satisfies Kuratowski's closure axioms. Mainly, we prove that primal
topology is finer than the topology of a primal topological space. We provide
structure of base of primal topology and prove other fundamental results
related to this new structure.
