The church called Killossery (the church of St. Ossier in Irish) was built near the banks of the river in the seventeenth century. The parish of Killossery consisted of 2500 acres (10 km²) and over 380 inhabitants in the nineteenth century. The parish was so large at one point that it included all of Rolestown and Lispopple. The current church (pictured above) is named St. Brigid's Church and was built in the 1850s, and had some extensive repair work done in the late 1990s. The Big House (Rowlestown House) originally belonged to the Corbally family since to the Griffin family.
