The Geology Department houses teaching and research collections the first of which were acquired by Trinity in 1777. Currently the collections comprise over 100,000 specimens. The main palaeontological holdings include Irish Silurian and Carboniferous invertebrates, Mesozoic ostracods, and Upper Palaeozoic miospores. The rock and mineral collections largely date from the 1820s and contains both Irish and foreign specimens.

A number of displays on topical aspects of Geology can be seen in the entrance hall of the Museum Building which is open Monday to Friday, 9.00am to 5.00pm (currently closed due to COVID19). The hallway also contains skeletons of the iconic Pleistocene mammal, the giant Irish Deer, and various Irish and foreign decorative stones make up the pillars and the staircase.

The current Geological Museum was relocated to the Trinity Technology and Enterprise Center (TTEC) in 2014. Visits can be arranged by emailing the curator, Patrick Wyse Jackson or by contacting us at
