Arco Universidad de Concepción, University entrance building in Concepción, Chile.

Arco Universidad de Concepción is the main entrance building featuring three stories with fluted columns supporting a curved canopy structure. Inside, it contains classrooms, auditoriums, laboratories, and a library dedicated to biological sciences.

The building resulted from a 1946 national architecture competition that Edmundo Buddemberg and Gabriela González won. Their victory led to the realization of this landmark structure at the university's entrance.

The building was long known as Arco de Medicina because the Faculty of Medicine stood here; today the Faculty of Biological Sciences occupies it, with the departments of Physiology, Pharmacology, Pathophysiology and Microbiology. On Día del Patrimonio 2017 a second-floor laboratory opened to the public, and in 2022 the faculty again received visitors inside.

The arch stands at the campus entrance on Calle Janequeo, with the former Faculty of Medicine now across Calle Chacabuco. The building is open to the public during the Día de los Patrimonios each year, when laboratories such as the second-floor one opened in 2017 can be visited. Outside those open days, access follows the Faculty of Biological Sciences' academic use.

The allegorical relief on the curved canopy was made by Argentine sculptor Mario Ormezzano and has been restored twice, in 1987 and 2006, by sculptor Luis Escalona Montalva, who also worked on the Casa del Arte and Casa del Deporte. The building's plans, including floor plans and facade details, are kept in the Archivo Luis David Cruz Ocampo.
