Place & story

The castle beside the Suir

The castle ruin on the River Suir was already a prominent feature of Newcastle when Samuel Lewis described the parish in 1837. He traced its ownership from the Birmingham family to the Prendergasts and then to the Perrys around the time of the Williamite Revolution. The older church was also ruinous, with its western window and parts of its walls surviving. Nearby, the Catholic chapel had been built about twenty years before Lewis's account and had subsequently been enlarged. [2]

A fair moved across the river

Lewis records a practical arrangement behind Newcastle's fair. Although the patent belonged to Mullogh parish on the opposite bank of the Suir, the fair was held at Newcastle by agreement because it offered better facilities for trading. Its date was 12 February. A dispensary, police station and fortnightly petty sessions added to the village's local functions. The arrangement shows that river boundaries did not prevent neighbouring communities from organising trade where it was most convenient. [2]

Liam Lynch in the Knockmealdowns

On 10 April 1923, Liam Lynch, chief of staff of the anti-Treaty IRA, was wounded by National Army soldiers in the Knockmealdown Mountains. He asked his companions to escape, leaving him to be captured. After being carried down the mountain and receiving medical attention, he died later that day. The National Museum preserves the uniform he was wearing, including a waistcoat marked by the wound. The surviving clothing provides a direct material connection with a death that came during the final weeks of the Civil War. [3]

A monument built by volunteers

Former comrades and supporters worked with Lynch's family to establish a memorial in the mountains. A committee drawn mainly from Newcastle, Goatenbridge, Ardfinnan and Knocklofty raised funds at home and in the United States. Its account records voluntary labour and sandstone gathered from the mountainside. The monument was unveiled in April 1935. James McGrath of Killeigh, Newcastle, and Maurice O'Gorman of Ardfinnan served as joint treasurers, recording subscriptions to the undertaking. The memorial became the focus of continuing local commemorations. [4]
