This article aims to document and understand the development of Ica culture and subsequent occupation of the Archaeological site Tacaraca, to encourage such research and cultural appreciation. As is known, the area of Ica was the scene of two major development of Paracas and Nasca cultures (800 a.C. to 600 d.C.), however, during the Late Intermediate Period (1000 -1470 d.C), after the Huari decline, Ica culture was the most important company that was established in the Ica valley and had as Tacaraca main center. The main buildings identified in the place match constructions administrative and religious well- planned structures that are interconnected by walkways and stairs leading to important architectural spaces with fine finishes.

The different works of archaeological exploration carried out in the area from the district of San Pedro de Larcay, province Sucre, department of Ayacucho, they have allowed to identify numerous archaeological sites that correspond to different cultures that were developed in this part of Peru. The archaeological evidences belong to societies that were developed as of the Period Average Horizon until the Inka time. Nevertheless, the presence of other sites with earlier occupation does not discard, since in the sector of Chiqnajota and Tororayoq-Huahuerqa has identified fragments of early ceramics. The archaeological sites of greater importance and than deserve to carry out futures works of archaeological investigation are: Chiqnajota, Raqayniyuq, Kallpa, Llako, Qasamarka, Wallpawiri, Iglesiachayuq, Sillacha, Karpani and Kullkuncha.

This article is a synthesis of the results of research work carried out during the years 2008 and 2009 in the area of the district of San Pedro de Larcay, which provided the documentation about 29 archaeological sites corresponding to different periods of cultural occupation, these works, indicate that the valley Chicha - Soras and its principal tributaries constituted a very important area where pre-Hispanic societies developed from the Formative Period until the Late Horizon Period. In the course of this time, societies that settled in these areas had their own forms of organization and development, production of pottery, architectural features and different forms of domain and use geographical, aspects of which by the way are own and distinctive from each other and allowed us to identify cultural of each one of the archaeological sites filiation.
