Recorded as an earthwork by the Sites and Monuments Record in 1986, this enigmatic structure sits 992 feet above low water mark, surrounded by what was once a fir plantation. The Ordnance Survey Namebook from 1838 offers a tantalising glimpse into its condition during the 19th century, describing it simply as ‘a pile of castle’, suggesting that even by then, the structure had fallen into considerable ruin.

The castle’s absence from the Record of Monuments and Places in 1995 raises intriguing questions about its historical significance and current state of preservation. This discrepancy between official records highlights the challenges faced by archaeologists and historians when documenting Ireland’s vast array of medieval sites, particularly those that have deteriorated beyond easy recognition. The location within a plantation suggests the site may have been deliberately obscured or protected by tree cover, whether by design or through natural regeneration of the landscape.

Today, visitors to Boystown might find little more than earthen mounds and scattered stones where this castle once stood, yet these humble remains represent centuries of Irish history. The elevated position would have offered commanding views across the Wicklow landscape, making it an ideal defensive position during turbulent medieval times. Like many of Ireland’s forgotten castles, this site serves as a reminder of the countless fortifications that once dotted the countryside; silent witnesses to a complex past that continues to reveal itself through careful archaeological investigation and local historical research.
