People walking around Dublin

Dear Collegues

Welcome to the 2024 PPS/SPP Meeting section

This year's meeting will be a joint meeting with the SPP and will be held in the fantastic city of Dublin, Ireland on the 12 - 14th September 2024


Early Bird Registration closes 30th June


Abstract Submission Closes on 24th May

On Saturday (14th September), we have a fantastic outing to Glendalough ('Glenn da loch' - the valley of two lakes)

Departing from Dublin city, heading south towards the Wicklow Mountains for a great trip to the "Garden of Ireland." As we leave the city we pass by Sugar Loaf mountain and descend through Ireland's highest village Roundwood on your way to magnificent Glendalough.

Renowned for its magnificent scenery and rich and varied heritage in terms of history and archaeology, Glendalough is famed for the Braveheart wedding scenes and it really is one of the most beautiful visitor sites in all of Ireland. You will have 2 hours to explore the deep valley with its ruined Monastic City of Celtic crosses, round towers and much more. Known as the valley of 2 lakes, we enjoy a leisurely stroll along the bank of the river, through the woods where we are greeted by babbling brooks, crystal cascades and the lakes of Glendalough. A real picture perfect moment.

You can book this excursion when registering for the upcoming meeting.

We hope that you will bring some extra time with you to explore this beautiful island, or return soon to take in the sights and sounds at your leisure and immerse yourself in some Irish culture. Here are some basic facts to give you a little socio-cultural background:

The island of Ireland was probably first settled ~10,000 years ago. Celts arrived from central Europe around 600B.C. There followed invasions by Vikings (8-9th century), then Normans (12th century) and then centuries of colonisation and rule by the English. In 1916, an armed rebellion, the Easter Rising started the process whereby Ireland gained its independence from its neighbour. This painful journey included the War of Independence (1919-1921) eventually leading to the Anglo-Irish treaty in 1922, a treaty that divided the island and brought the "Irish Free State" into existence.  The Free State, now the Republic of Ireland (Éire) constituted 26 of the island’s 32 counties, while the 6 counties in the North-Eastern part of the island became Northern Ireland and remained part of the United Kingdom. The  decision to divide the island was controversial at the time and triggered an Irish Civil War in 1922. It also contributed to the often fractious history of the North of Ireland throughout the 20th century. Happily this year we celebrate the 25th anniversary of an historic agreement, The Good Friday Agreement, that brought peace and a promise of progress for all on the island. Regrettably, Brexit has imposed new challenges on this process, taking Britain out of the European Union, when our shared membership had done much to facilitate progress.

The famine of the 1840’s saw the Irish population fall dramatically from a peak of 8.5 million with over 1 million deaths and a similar number leaving the country.   Emigration continued to be a feature of Irish life for much of next 150 years with hunger and economic disadvantage forcing family members to leave for foreign shores of myriad countries worldwide, most notably the UK, USA and Australia.  Indeed, there are now more people of Irish descent living elsewhere than reside at home here in Ireland. Each year, on St Patrick’s Day, major monuments across the world turn green in recognition of this Irish diaspora and the contribution they make to the many different communities who welcomed them.  Perhaps some of you are the descendants of Irish émigrés and plan to seek out your Irish roots while you are here!

Happily, the emigration narrative has been turned about.  Ireland has become a modern European country with a thriving economy and a young, energetic and highly educated workforce.  Indeed, the country has itself become a destination for immigrants from all over the world. Our population, estimated in 2023 at about 5.2 million,  is now far more diverse and multi-cultural than ever to fore.  In contrast to days gone by, you will hear many languages spoken on the streets of our cities these days!

While Ireland looks to the future with confidence, it also takes great pride in its history, culture and traditions.  English is the language spoken by the vast majority of Irish people, but the official first language of the Republic of Ireland is actually Irish (Gaeilge).  Gaeilge, a Celtic language, is spoken as a first language in a very small minority of communities, mostly along the West coast in Co. Cork, Kerry, Galway and Donegal as well as in Rinn, Co. Waterford.  However, Gaeilge is a core subject in all primary schools in Ireland and there has been a resurgence of education through the medium of the Irish language with 'Gaelscoileanna' proliferating nationwide. There are national TV and Radio channels dedicated to news and programmes 'as Gaeilge' (through Irish).

Irish people love sports.  Irish men and women have excelled at rugby, golf, soccer, rowing, sailing, boxing and athletics. The country has an international reputation for horse breeding and racing and a day at the races is a treat many visitors to Ireland enjoy.

The country also has its own uniquely Irish sports. These Gaelic games, principally Gaelic football, hurling and camogie thrive throughout the country and local Gaelic Athletic Association (GAA) clubs, where these sports are played, form the life-blood of rural communities.

Irish music and dance is a significant part of our culture. Alongside Gaelic games, these have been exported very successfully with our emigrants and are key components of their identity for many Irish overseas. Irish dance and music especially have been showcased in a commercial way literally on the international stage with “Riverdance” and other spin-off shows. You will be treated to an array of Irish traditional music and dance while visiting Dublin and we hope that you will join in!

For the best 'seisiún' (spontaneous traditional music-making and song) however you might find a rural pub in the west on a summer’s evening and there the 'craic' will be mightiest!  Something to particularly look out for is the 'sean nós' style of music and dance – this is the 

'old tradition' and especially entertaining in dance form! …and then there’s the soft shoe versus hard-shoed step dancing….

Irish musicians of course also include a few artists in other genres you may have come across, such as U2, the Cranberries, the Dubliners (Luke Kelly), Van Morrison, Sinéad O’Connor, Hozier, Rory Gallagher and Enya to name but a few.

Ireland has produced many literary giants including our 4 Nobel prize winners for literature: W.B. Yeats, George Bernard Shaw, Samuel Beckett and Séamus Heaney (visit the HomePlace) , as well as James Joyce (Come celebrate Bloomsday!), Oscar Wilde, Bram Stoker, Jonathan Swift, John McGahern, Brian Friel, Colm Tóibín and many more….

If you have the chance, don’t miss a great night at the theatre -either in the iconic Abbey theatre or the Gate in the heart of Dublin city!

A surprisingly rich literature in the Gaelic language also emerged in the 20th century from the tiny island community of the Blasket Islands off the Southwest coast in Co. Kerry.

And just a brief note about the weather – the only reliable observation is that Irish weather, while generally clement, is utterly unpredictable! Remember: there’s no such thing as bad weather only unsuitable clothing…

BRIEF VISIT (In and around Dublin):

Here are some ideas for what you might wish to get up to during your stay in Dublin, if it’s a brief one.

Dublin - Extend Your Stay For 24 Hours!

Dublin - Extend Your Stay For 48 Hours!

Before you arrive you can check what events are on in Dublin during your stay here: www.visitdublin.com


If /when you come back with a bit more time to spend, exploring the entire west coast which displays a diverse beauty unique to each county as you travel north to south or vice versa is highly recommended. The Wild Atlantic Way is a coastal route of over 1600 miles through some of the most beautiful scenery anywhere. Visit the old Viking settlements that became our cities of Cork, Waterford, Limerick and the gorgeous Kilkenny, which hosts a superb classical arts festival annually in August. Head to Wexford for the International Opera Festival held annually in October/November.

For a special treat, you might choose to stay in a country house or castle! Check out the Blue Book www.irelands-blue-book.ie

An archeological trip could take you around Ireland to see the oldest records of written Gaelic language carved on the mighty Ogham stones. You might then visit the ancient Neolithic passage tombs at Newgrange and Knowth, Ring forts, Round towers, Stone circles, Dolmens, Crannógs.  Early Christian monastic settlements including beehive dwellings are fascinating options that could take you out onto the Skelligs off the Southwest coast (Sceilig Mhicíl featured in Star Wars). See the beautiful illuminated manuscripts of the Irish monks (the Book of Kells) in Trinity College and visit the Long Room while you are on campus (also featured in Star Wars). From Dublin you can take a day-trip to beautiful Glendalough in the neighbouring county Wicklow.

Here are some links for a few options to explore if you have a longer time to spend here:





If you fancy popping up North, there are several sites well worthy of a visit, including the Titanic museum in Belfast, the spectacular natural wonder that is the Giant’s Causeway and for film fans there’s the Game of Thrones studio tour.

Go mbainfidh sibh taitneamh as bhúr dturas!           Enjoy your trip!

Your Local Organiser, Maureen O’Sullivan.
