Prettiest building on Trinity's campus. Inside is a small exhibit with various rocks and fossils and other geological phenomenon. Free to enter. Recently renovated and cleaned, the Venetian-Byzantine architecture of this building is a feast for the eyes and a delight for any art historian. Note the rare coloured marbles used in the columns, and outside the different floral decorations on each column.

The ball does not spin anymore. Fix this soon please.

Stunning, so much Connemara marble.

A must-see !

Home to Geology, Geography and civil engineering departments of Trinity College Dublin. Wonderful building both inside and out. Be sure to get inside to explore the architecture and variety of building stones.

Great architecture and interesting objects.

Stunning architecture.

Cool building. Lots of marbles and stones used in construction. Used as lecture theatres but downstairs open to the public.
