Following in the footsteps of Joaquín de Eleta. The modernization of El Burgo de Osma.

In January 1770, the Royal Decree established that no university in the kingdom should grant bachelor's degrees without having at least two chairs. Fearing closure due to the new dispositions and the lack of resources, the rector asked Eleta to prevent the loss of the professorships of the natives of the town. Founded in 1550, the University of Santa Catalina lived its splendor for almost two centuries, but closed in 1770. In 1778, the City Council asked Eleta to intercede, which he achieved by reestablishing it under the Patronato Regio. The monarch allocated funds and chairs were created in various faculties, marking the beginning of a brilliant era for the institution.

The Plaza Mayor and the Town Hall of El Burgo de Osma were born due to the need to build a new sacristy in the Cathedral and the chapel of Juan de Palafox, which forced the relocation of the Town Hall, which was attached to the Cathedral. The municipal activities caused constant disagreements with the Church. In the 18th century, the Hospital of San Agustín, key in the planning of the modern Burgo, served as a reference for the new square and Town Hall. In 1768, the transformation began with the demolition of the old Town Hall and the creation of the Plaza Mayor.

In the second half of the 18th century, Joaquín de Eleta played a key role in the development of El Burgo de Osma. In order to adapt the main square, he financed four houses to enclose the square, which he later ceded to the Hospital de San Agustín. His involvement led to the enlargement of the southern wall of the hospital, modifying its original structure. The new space housed convalescents, separating them from the common patients. In addition, an apothecary's shop was created, making the hospital a first-class hospital. Eleta, loyal to the hospital, financed its maintenance and donated the "Huerta de la Cadena". In 1773, after the works were completed, his coat of arms was placed on the south façade.

The Burgense Seminary, founded in 1583 for the formation of the clergy, was closely linked to the College-University of Santa Catalina, since its classrooms were in the university building, administered by the rector, and its income depended on it. After the extinction of the University, Calderón and Eleta proposed to strengthen the Seminary and make it independent. In 1779, Eleta, inspired by a Royal Decree of 1768, communicated his intention to create a college for college students of the bishopric. The City Council ceded the land, and in 1785 work began, directed by Luis de Bernasconi. Eleta, as bishop, supervised the Seminary, which continued studies after the suppression of the University. In 1787, he requested more land to expand the center, which was granted.

Joaquín de Eleta promoted the construction of the sumptuous Chapel of Juan de Palafox in the Cathedral of El Burgo de Osma, which prompted the need to expand the town. This project marked the beginning of an "architectural revolution" that laid the foundations of modern El Burgo de Osma. This transformation is also interpreted as a response to the confrontation with the city of Soria, which threatened to take over the episcopal see.

The construction of the Royal Hospice began with the request of the City Council to Eleta in 1783 to allocate a space for the underprivileged. The project was presented to Bishop Calderón and the Cabildo to ensure agreement between the institutions, backed by the Crown's interest in building this type of establishment in all the bishoprics. On April 23, 1785, the Cabildo ceded the land, and the king financed the works, under the direction of Luis Bernasconi, appointed by Eleta. The Hospice was completed in 1790, but with the end of Eleta's bishopric, its decline began.
