Although first mentioned in 1540, the Cingle fortified house was undoubtedly built in the second half of the 14th century by the Pèlerin family. Originally composed of a main tower and a wing back to the west, it perhaps originally included a curtain wall. During the 15th century, the south wing was extended towards the west, a main building comprising a lower room and an upper room was attached to the north of the main tower, while a turret occupied on the first floor by an oratory and on the second by a dovecote is built to the east, projecting. A wing including the kitchen on the ground floor is also built at right angles to the north of the courtyard. The farm itself retains some architectural elements dating from the 16th century.

The Bienassis fortified house, built by the Vallin family at the end of the 14th century, was organized around an enclosed courtyard and included a pavilion surrounded by watchtower turrets. The current building was completed in 1897 for Casimir Gournet, who wanted to give the old feudal residence the appearance of a medieval castle. Alphonse de Lamartine made several stays in Bienassis with his friend Nicolas Prosper Guichard, between 1804 and 1808. The castle, built of limestone rubble, consists of an L-shaped building covered with a long-pitched roof covered with mechanical tiles extended to the south by a high quadrangular tower with a porch in the work. The north wing has four levels of elevation: three cellars on the basement floor, a square floor and an attic floor. The tower rises on three levels: a ground floor with ribbed vaults and two square floors, the buildings are crowned with false machicolation. The corner turrets are covered with conical slate roofs. The stained glass windows of the ground floor living room are decorated with two bust-length women and two bust-length men in rondels. The coat of arms of the Joubert de Montlevon family can be found on one of the windows of the first living room on the ground floor. In the library, two shields with scrolling scroll motifs, a shield decorated with three female heads, a shield decorated with a passing griffin, and a shield decorated with two hammers with the initials C G for Casimir Gournet adorn the windows.

The Delphinal Castle (12th century), from the top of its strategic promontory, bears witness to the development of the city: construction of imposing fortified gates (14th century), a majestic market hall (15th century), a convent of Augustins leaning against the ramparts (14th-19th century) then its cloister (16th century)... So many vestiges which are the visible traces of a past where Crémieu had military, economic and religious importance. The medieval city of Crémieu is classified as a ZPPAUP (Urban and Landscape Architectural Heritage Protection Zone). Source: Isère Tourism
