Locally known as Fieldstone Castle, Fergus Castle is nestled in a small patch of woods surrounded by residential homes. The castle contains more then just the 15th century furnishings, it entombs the souls of tortured servants and peasants.

Transplanted from Ireland and re-assembled in Dover NH the castle is New Hampshire's only verified haunted castle.

The castle is in the process of being renovated to its 15th century condition. The castle which has been abandoned for 65 years was purchased from the City of Dover by a group of local historians in May of 1983.

The city sold the castle for one dollar with the understanding that the castle would undergo renovations and provide residents with a unique place to hold events and gatherings. years earlier, the city had subdivided the castle's estate to be sold for residential housing. The remaining castle grounds contain the castle and the Bossi family graveyard.

The cemetery is surrounded by mystery and controversy. The cemetery was thought to contain the remains of Bossi friends and family who died between the time the castle moved in 1903 and the time of Lord Bossi's death in 1918.
As part of the process to include the castle in the state historic site list, the state brought in a geologist from the US Geological Survey. The geologist would verify the origin and age of the stones and bricks that make up the castle.

Using radiocarbon dating techniques the geologist found that grave markers within the cemetery were not made from local materials, but were as old or older then the stones that make up the castle. Further investigation into the marketers found that the dates had been modified in the past 100 years.

In 1995 the historic society petitioned the Strafford County Superior Court to exhume the remains for carbon dating. The Court responded with :

"The request to exhume the remains located in Strafford County, Family Cemetery #5342, Plot #19 has been denied as the request does not meet the counties exhumation guidelines(document f3433), listed below for convince.

  • If an individual died under suspicious circumstances, a legitimate investigating agency may exhume the body to determine the cause of death.
  • Deceased individuals who were either not identified or misidentified at the time of burial may be reburied if survivors so wish.
  • Remains may be exhumed in order to be reinterred at a more appropriate location if requested by a family member."

The Historic Society believes Lord Bossi secretly moved the remains of his ancestors, to the cementary located on the castle grounds.

The US Army confirmed Sergeant Major Vincent Bossi was killed in the line of action in May of 1918, with his remains delivered for burial in Dover NH. The mausoleum located within the cemetery contains the remains of Lord Bossi.

During the October 2007 visit to the castle Helen "Nellie" Markantonatou the author of "Evil Castles of Europe" confirmed the history of the castle. Helen also provided information on the ownership gap. For a few brief years the castle was owned by a Scotsman Rayomond Sangster. This explains the presence of numerioius paintings of RedCap's and the replica of the Stone of Destiny.

The Stone of Destiny was taken from Scone by King Edward I of England in 1296 and remained under the Coronation Throne at Westminster Abbey in London for 700 years. However, there have always been theories that the Scots did not hand over the real stone !
