reopening saw the introduction of Monday closure, which has received criticism from the public and in the press. All NMNI sites are to close on Mondays. This decision is being reviewed by DCAL. Collections The museum has galleries covering the history of Northern Ireland from the earliest times to the very recent past, collections of art, mostly modern or ethnographic, historic and contemporary fashion and textiles, and also holds exhibitions. The scientific collections of the Ulster Museum contain important collections of Irish birds, mammals, insects, molluscs, marine invertebrates, flowering plants, algae and lichens, as well as an archive of books and manuscripts relating to Irish natural history. The museum also maintains a natural history website named Habitas. In the late 1980s and the early 1990s it had a permanent exhibition on dinosaurs which has since been scaled back considerably. There is also a collection of rocks, minerals and fossils. Irish archaeology The museum contains significant finds from Northern Ireland, although in earlier periods these were often sent to the British Museum or later Dublin, as with the Broighter Hoard, now in the National Museum of Ireland. Objects in the museum include the Malone Hoard of 19 polished Neolithic axe heads, the Moss-side Hoard of Mesolithic stone tools, the important Downpatrick Hoard of Bronze Age gold jewellery, part of the Late Roman Coleraine Hoard, the Viking Shanmullagh Hoard, and the medieval coins in the Armagh City Hoard and Armagh Castle Street Hoard. There are other significant objects of the Bronze Age gold jewellery for which Ireland is notable, including four of the 100-odd surviving gold lunulae, and some important early Celtic art, including a decorated bronze shield found in the River Shannon, and the Bann disc, bronze with triskele decoration.
