[1] If Brecan was the founder, as tradition states, it would have been one of the first central mission churches in Clare.

[3] Brecan also founded what is now called Carntemple about 2 miles (3.2 km) to the east of Doora Church.

[5] According to John O'Donovan and Eugene O'Curry, writing in 1839: The old Church of Dúiré is situated in the middle of a bog, about one mile to the south east of the Abbey of Ennis.

[6] At the distance of thirteen feet seven inches to the east of this doorway there is in the same wall a very ancient window, round-headed inside and outside.

At the distance of eleven feet eight inches to the east of this window there is another nearly of the same shape, but not so ancient, it having been evidently inserted to match the former when the Church was remodelled.

The former of these windows has a channel and rope (rabbit) on the outside and a representation of the head and breast of a very large dog (evidently the Irish wolf dog) placed at the height of one foot over it; the latter window has not the channel (architrave) or rope (cable moulding) and the only ornament it exhibits is a semicircle raised on the stone which forms its top.

It resembles the southern doorway on the Cathedral of Glendalough which led into a similar lateral (Iardom) building.

It is my opinion that this gable originally contained but one window, and this the more southern one above described, which was first placed in the middle of the gable, but when the Church was remodelled it was removed some feet out of its original position, and this northern one placed alongside it, and constructed, as well as the taste of the times would allow, to match it.

The more northern window in the south wall of this Church is obviously of the same age with the more southern one in the east gable, and the more eastern window in the south wall is of the same age with the more northern one in the east gable.

“Durinierekin,” in 1189; “Dubdery,” in 1302; “Dura,” in O’Brien’s Rental, 1380: “Dubhdoire,” [128] in the Life of St. Brendan MacFinloga.

[7] A website maintained by King's College London recorded in 2015 that the church had changed little since it was described by Westropp, apart from the fact that the arch stone of the west window of the south wall had fallen to the ground to the south of the church.
