The remains of the early 18th church of the Holy Trinity in Castlerea, County Roscommon. This building, and surrounding graveyard, stand in what had been part of the demesne owned by the Sandfords, who owned much of the land in this part of the country. The church ruins are notable for an exceptionally fine limestone Venetian window set into the building’s east gable. The graveyard is the burial place of Oscar Wilde’s grandfather Dr Thomas Wills Wilde, who practised medicine in the town and whose father, Ralph Wilde, acted as land agent for Lord Mount Sandford. The church was abandoned in the early 19th century when a new one was built on higher ground in the town.
