Purpose-built in 1890, the museum houses the country's archaeological collections. An audiovisual presentation helps put into context the masterpieces of Irish art displayed in the Treasury, with precious objects ranging from the Bronze Age to the 15C. Viking artefacts, reliquaries and crystal glass are on display, as is the reconstitution of a passage grave and a huge Lurgan longboat (2500 BC). The museum also boasts an Ancient Egypt section and another entitled the Road to Independence.
