St. Fachtna’s Cathedral.The Cathedral Church stands on a site where Christian worship has been offered since the time of St. Fachtna at the end of the sixth century. The earliest mention of a church building is in the 10^th century Book of Ballymote. Ross diocese was created by the Synod of Kells in1152. In 1198 there was a disputed episcopal appointment and the Dean was accused of stealing the consecrated oils and Mass books.  In 1517 a substantial cruciform building occupied the present site. This was either rebuilt or renovated in the latter years of the 16^th century. The Cathedral suffered extensive damage during the rebellion of 1641. After that the Cathedral was again rebuilt with a tower and spire. The spire had to be removed in 1793 and the current one erected in 1806.The early 19^th century witnessed many changes to the building. These included building the south and north transepts, the former containing a gallery for Lord Carbery. When Dr. Isaac Reeves became Dean in 1876 he began a major restoration resulting in the development of the Cathedral to its present form.The existence of a round tower is recorded in 1285 and it is mentioned again in 1517. It appears that it was destroyed in 1641. A tower is depicted on the seal of the Dean and Chapter.
