Heritage Week 2007, running from 25th of August to the 2nd of September, is one of the most comprehensive yet, with quite a lot of architectural events taking place, including just some listed below:
Architecture and History of the Royal Hospital Kilmainham: special tours of the site which is never open to the public as a touring destination, encompassing the Chapel, Master’s Quarters and grounds.
An Introduction to the Work of The National Inventory of Architectural Heritage: a one-off talk by senior architect Willie Cumming on the workings of the NIAH, and how buildings are scheduled for protection.
Merrion Square Open Day: including special walks, talks and access to properties usually closed to the public. The Central Catholic Library on the Square are also hosting a free exhibition about its development and history.
Building for Government: a once-off tour of the architectural development and restoration of Dublin Castle and State Apartments, with special access to rooms normally closed from viewing.
Heritage Walk: commemorating the looting and burning of Mitchelstown Castle on 12th August 1922, the largest of all Ireland’s mansions to be destroyed in the 1920’s burning campaign, including memorabilia related to the castle and fire.
If the list is a bit Dublin-centric, it’s largely because specialised architectural events seem to be concentrated in the capital, with nationwide sites generally operating their usual routine only for free or reduced admission; there are however lots of once-off non-architectural events nationally.
