Located in the center of the village of Batalha, the construction of the Mosteiro de Santa Maria da Vitória, also called Mosteiro da Batalha, resulted from the fulfillment of a promise made by King D. João I, in thanks for the victory in Aljubarrota, on August 14, 1385, which secured him the throne and guaranteed the independence of Portugal.
The works lasted more than 150 years, comprising several phases of construction. This duration justifies the existence in its artistic proposals of Manueline Gothic solutions (predominant) and a brief Renaissance note. Several additions were introduced to the initial project, resulting in a vast monastic ensemble that currently features a church, two cloisters with outbuildings, and two royal pantheons, the Founder's Chapel and the Imperfect Chapels.
D. João I donated the Monsatery to the order of S. Domingos, a donation to which the good offices of João das Regras, chancellor of the kingdom, and Frei Lourenço Lampreia, the monarch's confessor, were not alien. Property of the Dominicans until the extinction of the religious orders in 1834, the monument was later incorporated into the Public Treasury. Today it is dependent on the DGPC and functions as a cultural, tourist and devotional space. As a National monument, it is part of the List of World Heritage Sites defined by UNESCO, since 1983.
