Place & story

A wide street and a weighing beam

Lewis's 1837 town consisted of a broad street between the Earl of Shannon's demesne and a bridge. Its market house had been built by Henry Boyle in 1757. Although regular markets had ceased, a beam and scales remained for weighing grain and other goods. Castlemartyr's corporation had formerly returned two members to the Irish parliament, until the Union ended that representation. [2]

People & connections

Richard Alfred Millikin's birthplace

The writer Richard Alfred Millikin was born in Castlemartyr in 1767. His works included The River Side and the much better-known Groves of Blarney. Lewis singled him out in the town's entry, placing a literary association alongside its history of charters, estate ownership and military conflict. Millikin's song helped spread the fame of another Cork landscape far beyond its locality. [2]

Henry Boyle's mansion

Lewis described the Earl of Shannon's mansion as a central block with a portico and two extensive wings. Its grounds included lakes, canals, woodland walks and gardens of unusual plants. The ruins of the Fitzgerald castle stood within this carefully arranged landscape, making an older stronghold part of the outlook from a later country house. [2]

The estate's continuing landscape

The manor house now forms part of Castlemartyr Resort. Its grounds retain streams, a lake, woodland and formal garden areas, including reconstructed classical parterre beds. The house and the older castle ruins remain distinct elements of the estate. Together they make the succession from fortified residence to landscaped country seat visible beside the village. [3]
