San Uk Ling Holding Centre

San Uk Ling Holding Centre, located in Man Kam To, Hong Kong, is a detention facility that opened in July 1979 primarily for housing illegal immigrants before their repatriation to mainland China. Its strategic location near the Man Kam To Control Point has made it a significant site for immigration control. The centre gained notoriety during the 2019 protests when it was used to detain protestors, leading to allegations of mistreatment and abuse, which the authorities have denied. Historically, it has also served various purposes, including housing Vietnamese refugees and political activists. The facility's remote location has raised concerns about the treatment of detainees and access to legal support, making it a focal point for discussions on human rights and police conduct in Hong Kong.
