From the village car park ([[:File:YGS_NORTROCK_FIG_06_1.jpg|Figure 6.1]]a, [NU 128 421]) walk to the largely 13th century Benedictine Priory and St Mary's parish church (13th century with later additions). Note the handsome red sandstone ashlar used in the Priory church which is reputed to have been brought from mainland shoreline quarries at Cheswick Black Rocks [NU 038 477], but could equally have been quarried from the eastern shore line of the island. The purple, reddish and white sandstones used in the parish church were certainly obtained from the Nessend area (Locality 8, [NU 131 438]); much dolerite from The Heugh has been used as the rubble core of the walls. All the sandstone ashlar has been weathered to some extent by the prevailing wind and rain. Particularly fine examples of deep reticulate weathering may be seen on the crossing piers in the Priory church.

This low island southwest of the parish church is only accessible at low water. No vertical contacts are exposed on the eastern margin of this segment of the dyke echelon, but the dominant joints on the island are sub-horizontal. The flat surface, which has a slight easterly dip, and which lies mainly below high water mark, is formed of chilled rock ([[:File:YGS_NORTROCK_FIG_06_2.jpg|Figure 6.2]]a). The lower amygdale zone can be traced in the low cliffs on the north and west shores of the island. On the east side there is a marked feature formed by a minor normal north–south fault zone (down-throwing c. 1 m to the east) which repeats the dyke sequence.
