The Dunimarle Castle you see today is an imposing building made up of a small 18th-century mansion house which was incorporated into a castellated villa. Grand architectural features were added including a three-storey wing on the east side, with mullioned and transomed windows and crenellated parapet, providing exceptional views. An orangery – a very large conservatory – was added where hothouse flowers and fruits could be grown. A castellated gateway with monumental iron gates, a castellated garden gate, drum tower, screen wall and an extensive raised terrace enclosing the forecourt were all added. Extensive garden grounds were also laid out and St. Serfs Chapel was built around 1870.
