The parish church is an 18th-century building on an early Christian site dating back to the 8th century.

Nigg Old has odd and curious features. In the churchyard is the "Cholera Stone," dating from the cholera epidemic of 1832. One of the elders, on coming out of the church, saw a cloud of vapour hovering above the ground. He believed it to be a cloud of cholera, tossed a blanket or cloth over it, and placed this large stone on top to keep it from escaping.

According to one tradition, inside the church, the beadle allowed an illicit still to be kept in the space under the pulpit.
