Carrigallen (Irish: Carraig Álainn) is a small village in County Leitrim, Ireland. It is located on the R201 and R203 roads in the east of the county. The English translation of Carraig Álainn is "beautiful rock".
The village is set between the north and south shores of Town Lake and is an excellent angling centre. In the centre of the town is the Corn Mill theatre which has an extensive and varied programme of entertainment from drama (amateur and professional) to variety shows, music and poetry. The theatre which has been recently refurbished has excellent facilities.
Killahurk Ring Fort can be reached 2 km from the village. The ringfort is 500m west of Carrigallen Lough and is a good example of an early medieval enclosure.
St. Patrick is said to have passed through this region. While there he baptised followers at St. Patrick's holy well in Aghawillin and before leaving the region he blessed the ancient graveyard of Errew. The 16th century graveyard is situated about 2 miles east of Carrigallen overlooking Gulladoo Lake.
Margaret Haughery (1813–1882) came from Carrigallen.
Theatre - The Corn Mill Theatre & Arts Centre
The tradition of Drama in Carrigallen goes back to the late 1800s. The present group was founded in 1963 as The Community Players and there has been no break in activity since that time. The group has competed on the festival circuit since 1970 and has reached the All-Ireland Open Finals in Athlone on nineteen occasions. In 1989 the group opened their own theatre - The Corn Mill Theatre and Arts Centre. In that year the name of the group was changed to the Corn Mill Theatre Company. In 1999 major renovations took place when the foyer, new dressing rooms, rehearsal and storage areas were built. The group has won the All-Ireland Open Drama Finals in Athlone on two occasions - in 1998 with Belfry by Billy Roche and in 2005 with Stolen Child by Yvonne Quinn and Bairbre Ni Chaoimh.
