A Taste for Gothic

S1 E5: After the introduction of cannon, and following a period of relative peace in Ireland, castles no longer served as military strongholds in the 18th and 19th centuries and instead were adapted into beautiful homes for the lordly and wealthy classes. This episode visits Dublin Castle; the magical Tullynally; Birr Castle, home to what was once the world's largest telescope; and Charleville Castle.
