Dunsink Observatory

Dunsink Observatory

Dunsink Observatory, opened in 1785, was the first building in Ireland specifically constructed for scientific research. Ireland’s greatest mathematician/scientist, William Rowan Hamilton, lived and worked here.

Originally part of Trinity College Dublin, it was purchased by the state in 1947 when the School of Cosmic Physics was established (as part of the Dublin Institute for Advanced Studies).

The Observatory is used nowadays mainly for public outreach,  workshops/conferences, and as visitor accommodation. Rooms can also be hired by external parties.

Opening Hours:
Visitor open nights are usually held twice a month from October to March. Weather permitting, visitors can view celestial objects through the historic Grubb Telescope. There are also audio-visual presentations, lectures on a wide variety of topics in astronomy, and question and answer sessions. Open nights are free of charge.
