"The Rev. E. B. Wallace, minister of Barr, in writing the Statistical Account of the parish, very quaintly remarks, in connection with the church, that 'there was a religious association for some years, but it has fallen asleep.' If we may be allowed to judge by outward signs, the spiritual state of the parish is not presently suffering from a similar cause, as two new churches have been erected recently in the village. The ancient church contained 390 sittings, and had a central seat reserved for the poor of the parish. It was built in 1653, when Barr was erected into a parish, formed out of the more remote parts of the adjoining parishes of Girvan and Dailly."
"The chief antiquity in the old churchyard is a tombstone erected in memory of Edward M'Keen, a Covenanter, who was shot, on the 28th of February 1685, by Cornet Douglas and his party. On the evening of that day, Douglas, with a company of 24 soldiers, surrounded the farm house of Dalwine, still standing about four miles above the village of Barr. On searching the house they discovered M'Keen, a pious young man, who was then on a visit from Galloway, hiding betwixt the gable of one house and the side wall of another. After asking him a number of questions, one of the soldiers had him by the arm, dragging him away, when the ruffian, Douglas, without any warning, or permitting him to pray, discharged his pistol and shot him through the head. A companion, named David Martin, who was apprehended on the same occasion, was brought to the same place, and, after the soldiers had turned off his coat, they set him upon his knees beside the mangled body of M'Keen. One of the soldiers, more humane than the others, entreated the Cornet to spare his life. Another cold-blooded murder was thus prevented, but the fright and terror so unhinged Martin's reason, that he became an imbecile to the day of his death."

There was a medieval chapel, known as Kirkdomines or Kirkdominay, located on the high ground above the River Stinchar, near the Auchensoul Farm. Howver, there are no visible memorials on this site.
By the turn of the 20th century, there were two churches remaining in the village:
The Parish Church, built in 1878 at the west end of the village at the expense of Mr Griffin an auditor of Edinburgh, to replace the first church referred to above.
The Angus Memorial Chapel built in 1892 by the Free Church of Barr. This church was closed in 1987 and is now a private house.
