Why stay in Offaly

Offaly — Midlands & Birr Castle

Offaly is Ireland's most underrated county. Birr Castle Demesne contains the world's largest telescope when it was built in 1845 — the Leviathan of Parsonstown, whose 72-inch metal mirror discovered the spiral structure of galaxies — set within one of Ireland's finest Victorian gardens. Tullamore Dew, Ireland's second-best-selling whiskey, is made nearby. The Slieve Bloom Mountains offer 50km of walking trails used by almost no one outside the county.
