Knocknagoshel (Cnoc na gCaiseal meaning hill of the stone ringfort) is an attractive hilltop village in North Kerry. It is located approximately 1.5 miles west of the N21, 10 miles from Castleisland and 6 miles from Abbeyfeale. Historically, Knocknagoshel is famous for the banner carried by local men at a rally addressed by Irish politician, Charles Stewart Parnell, in 1891: "Arise Knocknagoshel, and take your place among the nations of the earth!". The banner is commemorated with a plaque on the end of a house in the centre of Knocknagoshel village. An interesting festival that has grown from strength to strength over the past number of years was set up by Knocknagoshel Halloween Group, Mindana. They host an annual ghost trail which begins at the village church, continues along the Well Road and ends at the funeral home. The ghost trail began in 1994 and was originally designed for the local children but as the years progressed, its popularity grew and by 2009 there were thousands of people from every corner of Ireland attending the festival. The festival takes place on the Sunday of the October Bank Holiday weekend.
The Nelius O'Connor Traditional Music Festival takes place in November each year. Musicians, singers and storytellers come from all over to take part. The annual Patron Saint Festival, called "The Pattern" is held on the 15th of AugustKnocknagoshel Gym is a community project which has been running for the last nine years and in 2010 it won the Kerry County Pride of Place award. It can be found in the grounds of the Knocknagoshel G.A.A. Club.
Just outside the village is a steeply inclined field, which in 1923 was part of Baranarigh Wood, where five soldiers of the Irish Free State National Army were killed by a booby trap mine on 6 March during the Irish Civil War. The men killed at Knocknagoshel were three officers and two privates, one of whom was a local man. Lieutenant Pat O’Connor was targeted by the Anti-Treaty IRA because of his knowledge of the local IRA organisation and the men involved in it and because of the energetic manner in which he pursued the Anti-Treaty guerrillas. The soldiers were lured into the trap by false information about a Republican dug out in the area. The atrocity lead to a series of reprisals against the anti-treaty side and the Free State troops killed 19 Republican prisoners in County Limerick over the following two weeks.
