Synopsis In this thesis we study a range of questions related to the order structure of models of first-order Peano Arithmetic. In Chapter 1 we give necessary definitions and describe the current state of the subject in the literature survey. In Chapter 2 we study first properties of order-types of models of PA, give examples and place first restrictions on what the order-type of a model of PA can be. In Chapter 3 we study models generated by indiscernibles and prove that the model generated by a set of indiscernibles ordered as a dense linear order (C,
