On the hill, a set of hermitages was established during the colonial era, which later became chapels.

Possibly, one of the reasons for its importance was the presence of numerous quarries in the surrounding area.

In 1659, the hermitage dedicated to the Virgin of Loreto was built, and the hill also took the name. Later, the name Guadalupe was added because there was a chapel with that dedication in the area, which was destroyed in 1862.

In the late 17th century, the Loreto hermitage underwent some changes, and the exterior walls surrounded the interior chapel, sharing the roof and a single door with it.

The facade of the exterior temple consists of two sections and features Puebla-style mortar reliefs of the time.

The entrance to the Casa de Loreto itself is more elaborate, with a segmental arch where the reliefs of the jambs continue, the monogram of Jesus appears as a shield, and the shrine is preserved in the background.

This site gained logistical importance in the defense of the city due to its location. During the Battle of May 5, 1862, Loreto Fort was occupied by General Berriozábal's troops, while General Zaragoza positioned himself in Guadalupe. In fact, in recognition of General Zaragoza, the name of Puebla changed from Puebla de los Ángeles to Puebla de Zaragoza.

Regarding Loreto Fort, restoration works were carried out from 1936 to install the Museum of Warrior History, an initiative of concerned citizens of Puebla who wanted to preserve their city's heritage. In 1962, it came under the management of the INAH (National Institute of Anthropology and History), and the name was changed to Museum of Non-Intervention.

The current exhibition of the museum consists of the collection gathered for the first museum, enriched with some additional pieces, all related to Mexico's wars in the 19th century.

This complex covers an area of approximately 1,500 square meters and includes a beautiful chapel dedicated to the Virgin, the chaplain's house, a military barracks, and 4 circular bastions. Additionally, the fort is surrounded by a moat that encircles it entirely.

The museum's collection is divided into seven rooms, starting with the one dedicated to the chapel of the Virgin of Loreto. The other rooms display various objects such as weapons, flags, documents, oil and acrylic paintings, personal items, and military clothing.

Moreover, the fort showcases several cannons from the 18th to the 20th centuries in the esplanade.
