Angela Maria de la Concepción, a Trinitarian nun from the convent of Medina del Campo, created the Monastery of the Trinitarian Nuns in El Toboso in 1680. It is a Spanish asset of cultural interest. The first monastery of the new branch of Trinitarian Recollect Nuns was located in El Toboso during a time of reform in the Catholic Church. The monastery retains the sobriety of a monastery while having outstanding architectural beauty. The Trinitarians of El Toboso are currently devoted to the contemplative life, which connects prayer and work hours. The neighborhood creates textiles and other handicrafts, and its hostel welcomes visitors.

With the assistance of Father Olivera, a Trinitarian, it was established in the 17th century by Angela Maria de la Concepcion. The founder's untimely demise at the age of 41 stopped the growth of this new Trinitarian branch. Consider nuns, whose proliferation did not occur until the 19th century thanks to new foundations. The nuns, who have continuously resided there since the monastery was constructed, with the exception of a brief period during the Spanish Civil War, have lived there. The community has endured the various vagaries of history throughout its more than three centuries of existence. With the loss of its farms, vineyards, and other land-based assets, the village suffered severe losses from the Napoleonic invasion and the disentailment.

1860 saw the establishment of the Trinitarian Recollect Nuns' second convent in Suesa, Cantabria, thanks to Mother Cruz, an El Toboso nun who was also Santander-born. In May 1860, she and four other sisters departed El Toboso for the brand-new establishment. The community was exterminated from 1936 to 1939 as a result of the Spanish Civil War. Following the Second Vatican Council's invitation, the Trinitarian Nuns merged into a single branch. The three branches—Calced, Discalced, and Recollect—became one order with the same habit and cross as a result.

By means of a decision issued on the 31st of the same month in the Official Gazette of Castilla-La Mancha, it was designated an Asset of Cultural Interest in the category of a monument on March 2, 1993. (DOCM).

Because of how plain it is, the Herrerian-style building is stunning. It has a serious and solemn air to it. Two towers on the main façade, each with a stone coat of arms, and a rectangular floor plan with two stories and a semi-basement. The main entryway has one of these coats of arms above it, while the narrow belfry has the other. The church's entrance door, which is of simpler construction, is located on the opposite façade. The quadrangular enclosed cloister is centered in the building's central courtyard. Tempera was used to embellish the cloister's galleries, which is still clearly visible today. The single-nave church with side chapels contains a canvas painted by Felipe de Castro (Portuguese), a follower of Claudio Coello (chamber painter to Charles IV in the 17th century). It stands for the Trinitarian Order's ethos and spirituality.
