Unidad Penal 9 de La Plata

Unidad Penal 9 is a former detention facility in La Plata that held political prisoners in multiple cell blocks during Argentina's military dictatorship between 1976 and 1983. The grounds contain several structures where exhibits now document firsthand accounts and evidence from those who were imprisoned there.

This prison operated as part of a network of detention facilities used during the military regime for state repression. The facility was involved in documented cases of killings and forced disappearances that characterized the regime's systematic violence.

The site functions as an educational center where visitors learn about human rights violations and participate in remembrance events for those affected. People gather here to honor the memory of those who suffered and to ensure their stories remain known.

The facility is located in the Villa Elvira neighborhood on 76th Street between 9th and 12th Streets. Visitors should set aside time to explore the various exhibits and read the documented accounts carefully.

Three medical professionals who worked at the prison were convicted in 2010 for their involvement in crimes against detainees. This case demonstrated how accountability extended even to healthcare workers who participated in the system.
