The Browne Clayton Monument is the only internally accessible Corinthian column in existence and is thus a hugely important and unique international architectural landmark. It stands on on Carrigadaggan Hill in Carrigbyrne, County Wexford. It was built of Mount Leinster granite and contains an internal staircase leading to the Capitol, from which an impressive view of the surrounding countryside can be obtained.

Its construction commenced in 1839 and was completed in 1841 and is a replica of what is known as Pompeys Column in Alexandria, Egypt, which is some 10 feet lower in height. It was built by General Robert Browne - Clayton of Carrigbyrne in commemoration of Sir Ralph Abercrombie who was his commanding officer with whom he fought and was victorious in the Egyptian battles in 1801 against Napoleon. It was at these battles that Abercrombie was mortally wounded.

On 29th December 1994 the column was struck by lightning and considerable damage was caused to the Capitol and the top third of the column. The restoration of the column was initiated and overseen by the Wexford Monument Trust Ltd which consists of representatives from Wexford County Council, the World Monument Fund in Britain and An Taisce.

Access is limited to specialist groups and only with prior notice. The monument and surrounds contain hazards for which great care is needed.
