Chillingham Castle - Northumberland, England

Location: Northumberland, England
History: (from wikipedia) The castle was originally a monastery in the late 12th century. In 1298, King Edward I, or "Edward Longshanks", stayed at the castle on his way to Scotland to battle a Scottish army led by William Wallace. A window was specially installed for the king, a rarity in such buildings at the time.
The castle occupied a strategically important location in medieval
times: it was located on the border between two feuding nations. It was
used as a staging post for English armies entering Scotland, but was
also repeatedly attacked and besieged by Scottish armies and raiding
parties heading south. The site contained a moat, and in some locations the fortifications were 12 feet thick.
The building underwent a series of enhancements, and in 1344 a license was issued by King Edward III to allow battlements to be built, effectively upgrading the stronghold to a fully fortified castle, of quadrangular form.

In 1617, James I, the first king of both England and Scotland, stayed at the castle on a
journey between his two kingdoms. As relations between the two
countries became peaceful following the union of the crowns, the need
for a military stronghold in the area declined. The castle was
gradually transformed; the moat was filled, and battlements were
converted into residential wings. A banquet hall and a library were built.
In the 18th and 19th century the grounds underwent landscaping, including work carried out by Sir Jeffry Wyatville. The once extensive park, now under a separate ownership from the castle, is home to the famous Chillingham Wild Cattle.

During World War II, the castle was used as an army barracks. During this time, much of the
decorative wood is said to have been stripped out and burned by the
soldiers billeted there. After the war, the castle began to fall into
disrepair. Lead had been removed from the roof, resulting in extensive
weather damage to large parts of the building. In the 1980s, the castle
was purchased by Sir Humphry Wakefield, 2nd Baronet,
whose wife Catherine is remotely descended from the Greys of
Chillingham. He set about a painstaking restoration of the castle. The
castle is now run as a country house hotel by the Wakefields.
Witnesses: (from wikipedia, a quick idea...) The most famous ghost
of the castle is the "blue (or radiant) boy", who according to the
owners used to haunt the Pink Room in the castle. Guests supposedly
reported seeing blue flashes and a blue "halo" of light above their
beds after a loud wail. It is claimed that the hauntings ceased after
renovation work revealed the body of a man and a young boy bricked
inside a 10-foot-thick wall. The owners also claim that the ghosts of John Sage, a former torturer, and of Lady Mary Berkeley haunt the castle.

The interesting part of the Pink room is the Blue boy. The blue boy is apparently the ghost of a young boy who had failed in brick laying. His punishment was to be buried alive within the walls of Castle. In the 1950's during renovations, the skeletal remains of a young boy were found in the walls of a passage way between the Pink room and an adjacent room.

It is said that while you walk through the tunnels you can hear the boys cries for help. But the further down the tunnel you go you can begin to hear a woman humming. EVP's have been captured in this location by television production teams, but I've yet to find them on the internet.
