A 22-year-old has admitted to breaking into a cottage associated with Swinstead Hall, after his DNA was found at the scene.
Scott Osborn of High Street, Grantham, pleaded guilty to attempted burglary with intent to steal on October 9.
The court heard from prosecutor Tracey Ross how the occupant of the cottage had been away at the time, but a member of staff at the Hall noticed that a pane of glass in the window was smashed and this was reported to police.
On searching the property they found that items had been thrown about the room, but nothing identified as having been taken.
A DNA swab was taken from the scene from which Osborn was identified and subsequently arrested.
Defending, Sonia Bhalla asked credit to be given to her client for his early guilty plea.
Magistrates adjourned the case for a pre-sentence report to be prepared, with Osborn due to appear again on January 26.
Until then he must comply with a curfew as part of his bail conditions to reside at his home address every night from 9pm to 7am.
