The 3rd Earl of Rosse built the largest telescope in the world in 1840. The castle is located in Offaly which is around a 2-hour drive from Dublin but it is well worth the trip.
16. Doonagore Castle

Doonagore Castle is a superb 16th century Irish castle, built to better monitor the comings and goings of ships on the Atlantic.
