An Taoiseach Liam Cosgrave opens Marlay Park in Rathfarnham, County Dublin.

Marlay Park is a 86 hectares suburban public park located in Rathfarnham, County Dublin. The wooded demesne lying 10 kilometres outside the city centre was acquired by Dublin County Council in 1972 for about £500,000. 

Marlay Park is officially opened by local man An Taoiseach Liam Cosgrave. The ceremony is attended by Minister for Education Richard Burke, Minister for Local Government James Tully, Ruairí Brugha Teachta Dála (TD) as well as many families from the surrounding areas of Ballinteer, Dundrum, Churchtown, Rathfarnham and Tallaght.

Marlay Park comprises woodlands, ponds and walks as well as football pitches and facilities for most types of sports. In his speech the Taoiseach reminds those present to take pride in such amenities and condemns vandalism which often ruins such facilities elsewhere. He announces,

This amenity of Marlay Park is now available for public use and it's a valuable public amenity worth maintaining as such, and formally declare this park open, and wish all who come here happiness, tranquillity and peace and pleasant recreation.

The Dublin Concert Band performs at the opening ceremony and the occasion is also marked by a special sports day for local people.
