Leinster were formed in 1875, one of the four provincial rugby teams in Ireland. Since rugby went professional, these four teams became the four professional teams, still run by the Irish Rugby Football Union (IRFU).
In amateur days the four provinces played against each other in the Interprovincial Championship and also played touring sides (usually midweek).
The Leinster 'Lions' roared into existence during the 2001/02 season, the result of a joint marketing initiative between Leinster Rugby and its kit sponsors, the Canterbury Clothing Company (CCC).
Leinster play in Donnybrook and have development plans to build a new 12,500 capacity stadium - from its existing 7,500 packed participating pilgrims!
The Lions train in the adjacent Old Belvedere Rugby Club and the David Lloyd Riverview Centre. 14 of the current squad are in the full Irish international squad with many others on 'A' duty.
Within Donnybrook itself there are two bars, in the Bective Rangers and Old Wesley Clubhouses. Until the new stadium is built the Lions will use Old Belvedere for pre and post match functions. Nearby bars include Kiely's (La Finezza Restaurant upstairs), Madigan's and Long's.
Jury's Burlington Hotel is also a popular watering hole and its Anabel's Nite Club is a favourite among rugby fans worldwide. Furama (Chinese), Casa Pasta (Italian) and Khan's Balti house (Indian) are across the road and three takeaways are within 5 minutes walk.
Tickets and merchandise are sold in different retail outlets both in Donnybrook and in Dublin's city centre. The Club Shop on Grafton Street and Magee's on adjacent Wicklow Street provide a comprehensive range and Elvery's on both Dawson Street and Suffolk Street are also worth a stop. On match days the Club have a retail shop at the ground - open 90 minutes before kick-off.
Should the Leinster Lions have a game at Lansdowne Road then add the Berkeley Court and Jury's Hotels, Crowe's and Paddy Cullen's to the list of bars plus the two clubhouses inside the ground at Lansdowne and Wanderers - no shortage of meeting places!
Their website, www.leinsterrugby.ie is again one of the four provincial sites, recently revamped by the IRFU.
The amateur Leinster sides previously played in a plain navy jersey with white shorts and navy socks. The Leinster Harp is an ever-present on the jersey.
The capacity at Donnybrook is currently 7,500 - and it is always packed to capacity
The Lions have three season tickets currently on offer - the 150 Club, the Lions Club and the Blue and Gold Club. Special tickets for schoolchildren are provided and old-fashioned cash is sometimes taken at the turnstiles.
Fans sing 'Molly Malone', 'Rare 'Aul Times' and join in the U2 and Thin Lizzy songs that buzz around the ground.
Being a provincial side many other Leinster and Irish songs are added to the 'play list' and team mascot, Liam the Lion, has no trouble in raising a chorus!
