Built around 1500 by the MacCoughlan clan, Clonony Castle is a classic example of a Tudor-era tower house. It was later seized by King Henry VIII and granted to Thomas Boleyn, father of Anne Boleyn, as part of the political manoeuvring that defined the Tudor court. While Anne herself never lived here, her cousins Mary and Elizabeth Boleyn are recorded as having stayed at Clonony—and are believed to be buried nearby.

The castle includes many defensive features typical of its time: narrow stone spiral staircases, a murder hole above the entrance, arrow loops, and concealed chambers. Extensive restoration work in recent years has stabilised the structure, reinforced vaulted ceilings, and partially rebuilt the bawn wall. In 2022, the castle was listed for sale, showcasing a beautifully restored interior that blends medieval architecture with modern comfort.

For decades, reports have surfaced of a tall, thin figure appearing on the top of the tower. Often described as skeletal and glowing, the figure is seen wearing various forms of historical clothing—ranging from peasant garb to what looks like a hazy suit of armour. Sightings usually come from passing motorists, who are drawn to the softly glowing presence above. Some stop to get a better look, only to watch the figure fade away.

One account describes the ghost as a sentry holding a long object, like a pike or broom, standing perfectly still. Another witness reported turning their car around in disbelief—only to find the tower deserted when they returned. According to local tradition, the spirit may be that of a soldier killed while on duty, still keeping watch from the battlements.

In 1803, workers near the castle uncovered a small crypt containing two skeletons beneath a carved tomb slab. A later rubbing confirmed the identities as Mary and Elizabeth Boleyn. While their remains were reinterred, the slab remains in place. Local folklore suggests the slab also covers an entrance to a subterranean cave—rumoured to be haunted by a more malevolent spirit—but no verified sightings have ever been recorded.

Visitors to the castle have also reported distant whispers, phantom footsteps, and unexplained door movements. Faint lights have been seen in the upper levels, believed to be unrelated to the glowing tower figure. Paranormal investigators have captured unusual EMF readings and temperature drops, particularly on the second floor and near the tomb slab.
