Marian Manor, the nursing and rehabilitation facility in South Boston run by the Carmelite Sisters for the Aged and Infirm for the last 70 years, will close this summer. The group notified the state’s Department of Public Health of its plan on Tuesday.

In a statement to the Reporter, a spokesperson for the Sisters explained: “Despite our best efforts to find a partner to redevelop the current location, we have been unable to create a plan that is financially viable given the challenges that all healthcare institutions currently face, including nursing shortages, skyrocketing real estate costs, inflation, and the growing demands for facility maintenance.

“In addition, there is not sufficient public funding or grants available at this time that would allow us to move forward with any of the redevelopment proposals considered for the current location.... Having exhausted every practical option, we have made the difficult decision to close Marian Manor as the aging building has come to the end of its useful life.”

The closure is expected to take effect in 120 days.

The Sisters say that “prior to the closure of the facility, we will ensure that all our current residents are relocated to another location of their choosing – including a nearby facility sponsored by the Carmelite Sisters, or another nursing and long-term care facility.”

The property on Telegraph Hill that the Sisters are leaving was the site where Andrew Carney built his eponymous hospital in 1863. The Carmelites opened Marian Manor in 1954, a year after the Carney Hospital moved to Lower Mills in Dorchester.
