Place & story

A town shaped by yarn

Oldcastle developed into an important eighteenth-century market town under the Naper family of Loughcrew. Meath's conservation appraisal describes its yarn market as the largest in the country. Trade concentrated on an elevated, irregular triangular square, with streets extending along four of the five approaching roads. The Napers' improvements gave the town much of its Georgian appearance. The approach from Castlepollard still reveals the way its commercial centre occupies the higher ground. [2]

The Naper Arms on the square

The Naper Arms Hotel, built around 1860, presents a substantial three-storey frontage towards the former market house. Its Tuscan entrance porch and elaborate rendered decoration made an imposing statement in a trading town. Pilasters articulate the corners, while the treatment of the windows distinguishes the different floors. These details provide a Victorian counterpart to the square's older market buildings and preserve evidence of the investment that commerce brought to Oldcastle. [3]

People & connections

Aloys Fleischmann in internment

During the First World War, Oldcastle Workhouse became an internment camp for almost six hundred foreign nationals. Among them was the musician Aloys Fleischmann, whose detention separated him from his Irish wife and son for more than four years. The National Library's wartime exhibition includes his experience among the lives displaced by the conflict. [4]

Objects made behind the wire

Rings made by an Oldcastle internee survive as evidence of craft within the camp. Noel French's object history also records contemporary reports of prisoners making intricate toys with pocket knives. Such objects give a tangible scale to this episode, alongside the administrative record of detention. The internees left Oldcastle on a special train in May 1918, travelling through Dublin's North Wall before their transfer to Knockaloe on the Isle of Man. [5]
