This episode features Dublin Castle, Oldbridge House, Derrynane House, and Pearse Museum - St Enda's Park, each one a centre of power.

Featuring properties built in the 18th,19th and 20th centuries, completely different in style and purpose, yet linked by their connection to imaginative and creative people.

A look at three sites dedicated to the memory of people who lost their lives fighting for different, sometimes opposing, causes. The properties are Arbour Hill Cemetery, The Irish National War Memorial Gardens in Islandbridge, The Garden of Remembrance and The JFK Arboretum.
