On the southwestern Sports Grounds of the town is the 15th-century tower house of Castle Matrix.
The castle was built as a fortress during the early 1400s by Thomas FitzGerald, 7th Earl of Desmond, and was later the home of Maurice FitzGerald, 9th Earl of Desmond.
It contains a display of art objects and holds historical records and is one of a series of significant Desmond properties in County Limerick (see also Adare, Askeaton and Newcastle West).

In the cemetery of Holy Trinity Church are many gravestones bearing names of Irish Palatine families.
These families came from Rheinland-Pfalz, the Rhineland Palatinate in Germany as refugees in 1709.
Many of their descendants now live in North America, though the region around Castle Matrix in the villages of Killeheen, Ballingrane, and Courtmatrix contains the largest concentration of Palatine descendants in Ireland.
Rathkeale's former railway station on the closed North Kerry railway line from Limerick to Tralee has been converted into the Irish Palatine Museum.
