Callan, The Augustinian Friary on Mill Street. © Liam Murphy. According to a newspaper report, ownership was transferred to the local council in 2022. The remains of the medieval Augustinian Friary stands closely by to the north. Not well seen by Streetview (in 2023 for example), its Wikipedia article has some photos. The same article also says that the more  recent Friary was closed in 2001. Also not well seen on Streetview is the former St. Mary, on Green Street. Link has photos, and dates it to the 13th century, closing in the 1970's. A map of 1843 show R.C. Chap. on Green Street. Its footprint remains essentially unchanged, and is Church of The Assumption (R.C.) - 2025 Streetview. This source dates it to 1836-43. The Chapel of the Convent of Mercy (R.C.) can (just) be seen in a Streetview from 2009. An interior and exterior photo can be seen here.
