The Prelude, whilst J. M. W. Turner made numerous etchings of the abbey. Queen Victoria and her lady in waiting Augusta Stanley are known to have visited in 1848 based on the diaries of the latter. Other notable tourists include the Theodore Roosevelt family. It was the first unguided visit on their European tour. A young Teddy Roosevelt and his siblings played on the ruins, which, in 1869, were not roped off or restricted. In 1896, while touring industrial Northern England, Chinese statesman Li Hongzhang visited the abbey site. Viceroy Li stayed longer than expected, so that his schedule had to be rearranged. Conservation and protection The Furness Abbey complex is a Scheduled Monument and Conservation Area containing five Grade I listed buildings and structures. Restoration work took place between 2008 and 2017 amid fears that part of the abbey could have collapsed. Folklore and supernatural activity There are many stories and sightings claiming that Furness Abbey is haunted. There are supposedly at least three ghosts which have been seen numerous times at the Abbey. First, it is said that the spirit of a monk has been seen climbing a staircase and also possibly walking towards the gatehouse before vanishing into a wall. Another sighting is that of a squire's daughter. She was known to meet her lover at the ruined abbey after the Reformation, although one day her partner took a journey out to sea from which he never returned. It is thought that the girl went back to the Abbey every day until her death to the site she and her partner once loved; the track she walked is today still known as "My Lady's Walk." There have also been many sightings of a white lady, although due to possible conflicting stories, it is unclear whether the White Lady and the ghost of the squire's daughter are the same person or not. Possibly the most famous ghost of Furness Abbey is a headless monk on horseback, who rides underneath the sandstone arch near the Abbey Tavern; the death of this individual is linked to an invasion by the Scots in 1316. A tunnel is said to run underneath the Abbey to both Piel Castle and Dalton Castle, allowing the monks to receive supplies and keep watch upon the local settlements. It has also been rumoured that the Holy Grail and King John's missing jewels are hidden somewhere inside
