The Florence Nightingale Museum is to partially reopen with a series of open weekends throughout the rest of the year.
The institution, based on the site of St Thomas' Hospital, previously announced it had closed for the foreseeable future due to the financial effects of the pandemic.
Museum bosses said emergency funding from the Culture Recovery Fund meant it would now have a limited reopening with open weekends on the first full weekend of every month from June.
The museum's director David Green said: "We are extremely pleased to be opening our doors again, if only for a limited time.
"These will be very special, now-rare, opportunities to explore the life of the woman whose name has been used so much over the past year and whose legacy shines through the remarkable work of the health care professionals that have been fighting the pandemic."
