This charming castle is composed of three towers. The oldest appears to be the keep, a rectangular tower accessed from the first floor. Only a few narrow openings illuminate the interior. Its floors were entirely wooden. It is believed to have been built around 1360 by Cardinal de Colombier, lord of the manor. The round tower to the southeast, with its horizontal arrow slits, dates from the 15th century. This tower contains dungeons. The third, more recent tower dates from the early 16th century. Buildings adjoining the keep form a Renaissance residential wing. Another building was added or repaired at an even later date, in the 17th or 18th century.

The retention dam, located between the municipalities of Saint-Pierre-de-Boeuf – from which it takes its name – and Saint-Maurice-l’Exil, crosses the natural arm of the Rhône (right arm), connecting the town of Saint-Pierre-de-Boeuf to the Île de la Platière on the left bank. The 140 m wide dam has six 20 m passes equipped with 12 m high gates, separated by 4 m thick concrete piers. The dam bridge is a 174 m long reinforced concrete girder bridge (168.80 m opening), with seven 28 m spans. Over a width of 8.80 m, it carries a 6 m long, two-lane, two-way roadway, bordered by two sidewalks lined with parapets made of mixed material (concrete-metal). The upstream sidewalk is separated from the roadway by a low wall. Shelters are located on the downstream side of the piers. The ViaRhône cycle path continues on both sides.
