Galway Cathedral sits on the site of a prison. The county gaol opened here in 1810, closed in 1939, and was demolished in the 1940s, at which point Bishop Micheál Browne acquired the land to build one of the last great stone cathedrals in Europe. It opened in 1965, its dome at 158 feet still the tallest structure on the Galway skyline.

The full name, the Cathedral of Our Lady Assumed into Heaven and St Nicholas, hints at the scale. It seats 1,500 and runs 300 feet in length. Three men were hanged here in 1882 for the Maamtrasna Murders, their bodies buried in what is now the car park. One, Myles Joyce, was almost certainly innocent; he was formally pardoned by President Michael D. Higgins in 2018.

VoiceMap's tours connect the cathedral to Galway's history of imprisonment, wrongful execution, and the flowering of Catholic civic ambition after Emancipation.
