PRONI Document of the Month July 2015

To welcome the Tall Ships Races to Belfast, PRONI has chosen a volume with a maritime theme for its July Document of the Month.

The album focuses on Glenarm castle and demesne, one of the seats of the Earls of Antrim since the 17th century. It also contains views and sketches of the surrounding county and coastline where, as Lady Louisa puts it, “[the] scenery is grand and picturesque”.

More information can be found on our Document of The Month Page.

6th Connaught Rangers Exhibition, 4 June – 10 July 2015

PRONI will be hosting an exhibition of the 6th Connaught Rangers from the 4 June 2015 – 10 July 2015. The exhibition was curated by the 6th Connaught Rangers Research Group. Founded in 2006 and made up of volunteers with connections to men who fought during WW1, the group takes its name from the regiment that their relatives joined. Whilst concentrating on the 6th Connaught Rangers initially, research has expanded to those Belfast men who belonged to other regiments such as the 7th Leinsters. The 6th Connaught Rangers Research Group have used family stories, memorabilia, photographs, newspapers, archives and military sources to uncover the story of how their relatives came to fight in the war.
More information on this event can be found on our Talks and Events page.

Landmarks from Home Exhibition, 11th June to 26th June 2015

PRONI is delighted to be hosting a tapestry from Arts Care called Landmarks from Home which was inspired by the Northern Irish landscape. This textile piece was conceived by Arts Care Artists in residence Grainne Kielty and Cheryl Blakely and Artist volunteer Nicola Thornhill at Musgrave Park Hospital, Belfast.  Together with staff and patients who gave of their time, ideas and enthusiasm, this powerful artwork was produced.   
The piece, measuring 3 meters squared, took almost 9 months to complete.  Most of the fabrics used in its creation have been hand felted and embellished with threads beads and buttons.  It is very fitting that it should hang here in the Titanic Quarter since the ship itself features so prominently in the piece; and PRONI holds such a wealth of archival material relating to our local landscape, heritage and identity.

The doings of ships under sail: documents of marine life in PRONI

As long as ships have sailed, mariners have kept logs of their voyages, charted known and unknown waters and kept diaries of the loneliness and camaraderie of life at sea. After inspecting the tall ships on the quays of modern Belfast come to PRONI to have a look at the archives and see a display of fascinating and precious documents telling of life at sea. We have maps, charts, photographs of expeditions, majestic cutters and private yachts and neat fishing boats, records of Belfast Harbour and the works of Harland & Wolff during the 19th century when wooden sailing ships, great and small, were built in this neighbourhood (PRONI stands where the plating shop once stood), letters describing voyages to Labrador and the trials of passengers going to the New World, plans and drawings of the harbours of Ulster.PRONI will be conducting 2 tours a day on the Thursday and Friday during the event starting at 1and 3pm. Contact PRONI to secure your place on these for a chance to view original maritime documents in our reading room.
