Lovers of architecture and history will revel in a new summer exhibition opening this week at the Irish Architectural Archive on Merrion Square. It will feature original drawings for architectural projects undertaken the mid- to late 18th century by noblemen of the day, including members of of the FitzGerald family, Earls of Kildare and later Dukes of Leinster. Included are works by architects Isaac Ware, Thomas Ivory and Thomas Owen. Particularly noteworthy are the original drawings from 1745 by Richard Castle for Leinster House in Dublin.

The works are part of the Guinness Collection assembled by the Hon Desmond Guinness and his first wife, the late Mariga Guinness, in the 1960s.

Admission to the exhibition is free. See iarc.ie
