National Museum of Ireland in the context of "Crux gemmata"

The Royal Irish Academy (RIA; Irish: Acadamh Ríoga na hÉireann), based in Dublin, is an academic body that promotes study in the natural sciences, arts, literature, and social sciences. It is Ireland's premier learned society and one of its leading cultural and academic institutions. The academy was established in 1785 and granted a royal charter by King George III in 1786. As of 2019, the RIA has 600 members, with regular members being Irish residents elected in recognition of their academic achievements, and honorary members similarly qualified but usually based abroad; a small number of members are also elected in recognition of non-academic contributions to the Irish society. All members are entitled to use the honorific title MRIA with their names.

Until the late 19th century the Royal Irish Academy was the owner of the main national collection of Irish antiquities. It presented its collection of archaeological artefacts and similar items, which included such famous pieces as the Tara Brooch, the Cross of Cong and the Ardagh Chalice to what is now the National Museum of Ireland, but retains its very significant collection of manuscripts including the famous Cathach of Colmcille, the Lebor na hUidre (c. 1100), the later medieval Leabhar Breac, the Book of Ballymote, and the Annals of the Four Masters.

The National Museum of Ireland – Archaeology (Irish: Ard-Mhúsaem na hÉireann – Seandálaíocht, often known as the "NMI") is a branch of the National Museum of Ireland located on Kildare Street in Dublin, Ireland, that specialises in Irish and other antiquities dating from the Stone Age to the Late Middle Ages.

The museum was established under the Dublin Science and Art Museum Act 1877 (40 & 41 Vict. c. ccxxxiv). Before, its collections had been divided between the Royal Dublin Society and the Natural History Museum on Merrion Street. The museum was built by the father and son architects Thomas Newenham Deane and Thomas Manly Deane. The rotunda at the front of the National Museum matches that of the National Library of Ireland, which face each other across the front of Leinster House.

The Derrynaflan Chalice is an 8th- or 9th-century chalice that was found as part of the Derrynaflan Hoard of five liturgical vessels. The discovery was made on 17 February 1980 near Killenaule, County Tipperary in Ireland. According to art historian Michael Ryan the hoard "represents the most complex and sumptuous expression of the ecclesiastical art-style of early-medieval Ireland as we know it in its eighth- and ninth-century maturity." The area known as Derrynaflan is an island of pastureland surrounded by bogland, which was the site of an early Irish abbey. The chalice was found with a composite silver paten, a hoop that may have been a stand for the paten, a liturgical strainer and a bronze basin inverted over the other objects. The group is among the most important surviving examples of Insular metalwork. It was donated to the Irish State and the items are now on display in the National Museum of Ireland.

The hoard was probably secreted during the turbulent 10th to 12th centuries, when Viking raids and dynastic turmoil created many occasions when valuables were hidden. The early and later 10th century is marked by a particular concentration of hoarding in Ireland.

The National Museum of Ireland – Decorative Arts and History (Irish: Ard-Mhúsaem na hÉireann – Na hEalaíona Maisiúla ⁊ Stair) is a branch of the National Museum of Ireland (NMI) located at the former Collins Barracks in the Arbour Hill area of Dublin, Ireland.

This museum holds historical and contemporary collections relating to military history and decorative arts, with core collections relating to historical Irish events such as the Easter Rising.

Swords (Irish: Sord [sˠoːɾˠd̪ˠ] or Sord Cholmcille) in County Dublin, the county town of the local government area of Fingal, is a large suburban town on the east coast of Ireland, situated ten kilometres north of Dublin city centre. It is the eighth largest urban area in Ireland, with a population of 40,776 as of the 2022 census. The town was reputedly founded c. AD 560. Located on the Ward River, Swords features Swords Castle, a restored medieval castle, a holy well from which it takes its name, a round tower and a Norman tower. Facilities in the area include the Pavilions shopping centre, one of the largest in the Dublin region, a range of civic offices, some light industries, the main storage facility and archive of the National Museum of Ireland and several parks. Dublin Airport is located nearby.

The name "Swords" gives its name to a townland of Swords Demesne, a civil parish, and a local electoral area.

Collins Barracks (Irish: Dún Uí Choileáin) is a former military barracks in the Arbour Hill area of Dublin, Ireland. The buildings now house the National Museum of Ireland – Decorative Arts and History.

Previously housing first British Armed Forces and later Irish Army garrisons through three centuries, the barracks were the oldest continuously occupied example in the world. Built in 1702, and further extended in the late 18th century and 19th century, the complex's main buildings are neo-classical in style. Originally called simply The Barracks, and later The Royal Barracks, the name was changed in 1922 by the Irish Free State to Collins Barracks, in honour of Michael Collins, who had been killed earlier that year. Since 1997 the barracks have been home to collections of the National Museum of Ireland (for Decorative Arts and History exhibits), and the original structures have seen some award-winning redevelopment and conservation work to support this new role.
