Overview

Oldcastle sits in the north‑west of County Meath, just a short drive from the counties of Westmeath and Cavan. With a population of about 1,400 (2022), the town is a gateway to some of Ireland’s most impressive prehistoric monuments, notably the Loughcrew Cairns – often called the “Hills of the Witch”. The town centre clusters around The Square, where you’ll find a mix of traditional pubs, a SuperValu grocery, and a handful of take‑away eateries. Oldcastle’s location on the Boyne Valley Drive makes it an ideal base for exploring the wider archaeological landscape of the region.

History

The modern town of Oldcastle was largely shaped in the 18th century by the Naper family, who were granted lands from the Plunkett estate after the Cromwellian wars. Despite the Napers’ influence, the area retained a strong Gaelic character, which meant it suffered disproportionately during the Great Famine of the 1840s. Remnants of that hardship are still visible in the town’s layout and the surrounding farmland.

Oldcastle also played a unique role in the First World War. From 1914 to 1918 it hosted Ireland’s only permanent civilian POW camp, detaining enemy aliens and later German and Austrian soldiers. The camp’s site is now a housing estate just south of town. A Norman motte‑and‑bailey once stood where the town’s overgrown mound remains, hinting at the medieval strategic importance of the location.

What to See & Do

Loughcrew Cairns (Slieve na Calliagh)

Lough Erne
Tourism Ireland

Only three kilometres east of Oldcastle, the Loughcrew Megalithic Cemetery comprises a series of Neolithic passage tombs spread over four peaks. The most visited is Cairn T, a cruciform chamber crowned by a corbelled roof and decorated with some of Ireland’s finest prehistoric art. The cairns are aligned to the spring and autumn equinoxes, drawing small gatherings to greet the sunrise. While the interior of Cairn T is currently closed for conservation, the surrounding cairns (D, L, and the unexcavated Cairn M) remain accessible via well‑marked paths.

Opening times (2026 season): 28 May – 02 Sept, guided tours daily 10:30‑15:30 (weather‑dependent). The site’s car park is open year‑round.

Admission: Camping on the estate is €12 per person; the rest of the site is free to visit.

Accessibility: The steep climb to Cairn T is not wheelchair‑friendly, and the approach road is narrow. Visitors are asked to stay on the paths and avoid touching the stones.

Saint Oliver Plunkett’s Memorial Church

Located within the Loughcrew Estate, this modest church honours the native saint Oliver Plunkett (1625‑1681). It opens daily from 10 am to 5 pm and hosts an annual pilgrimage on 1 July, the anniversary of Plunkett’s execution at Tyburn.
