Burglars have caused "significant damage" at Charlton House one week after lead was stolen from the roof of another heritage site nearby.
An attempted burglary sometime on Monday morning, September 20, caused damage to the building in what was described as a "disappointing day."
Those behind Charlton House say they have reported the incident to police, and the area in question is now alarmed.
Just last week, Charlton Assembly Rooms, metres away from Charlton House, was targeted by burglars stealing lead from the roof of the building.
The Grade II listed rooms, which dates back to 1881, is now under repair following the "nasty surprise."
Royal Greenwich Heritage Trust said that "to say it has been a frustrating week for our team would be an understatement."
The team posted: "The damage done to both the Charlton Assembly Rooms and RGHT Charlton House & Gardens in the past week has been heartbreaking."
The damage to the assembly rooms was "particularly disappointing" as the lead had just been replace in June, and would now require more time-consuming work.
Charlton House has over 400 years of history, including being a hub during both the world wars, and is even thought to be one of the most haunted buildings in the UK.
The house was built between 1607 and 1612 for Sir Adam Newton, who was tutor to Henry, Prince of Wales, and is one of the finest surviving Jacobean manor houses in England.
Temporarily closed to the public, the site has recently hosted a Covid-19 vaccination centre, and can also be hired out.
