Admission to Office of Public Works managed heritage sites will be free on the first Wednesday of every month in 2011, beginning this month.

The initiative hopes to encourage more national and international people to visit the sites and to stimulate interest in the heritage of the country.

Minister of State with Responsibility for the Office of Public Works Brian Hayes has urged the public to take advantage of the opportunity.

Access to many sites is already free, but for some sites such as Kilmainham Gaol, Kilkenny Castle and Newgrange adult visitors pay a fee of between €3-€11 each.
