The British Columbia Penitentiary (BC Penitentiary, commonly referred to as the BC Pen and the Pen) was a federal maximum security prison located in New Westmnster, British Columbia, Canada. The BC Penitentiary operated for 102 years, from 1878 until it was decommissioned in 1980.
The BC Penitentiary site included a prison cemetery called Boot Hill, where this cache has brought you. The remains of most inmates who died at BC Penitentiary were claimed by their families; those that were not were buried at Boot Hill. All work relating to the cemetery such as digging graves, site maintenance, and the construction of grave markers and coffins, was performed by inmates. The cemetery officially opened in 1913, but was probably in use in 1912.
The remains of approximately 50 inmates are still buried here. During the cemetery's early years, records were not carefully taken or preserved, and are unreliable. Most graves are marked by small concrete gravestones engraved only with the inmate's prison number. Some inmates are buried in unmarked graves.
