In 2020, the congregation merged with that of Queen's Cross Church and the Kirk of St Nicholas ceased to be used for regular worship.

The Oil and Gas chapel contains wooden furniture made by the late Tim Stead alongside a stained glass window that depicts life in Aberdeen, created by Scottish artist, Shona MacInnes.

The earliest mention of a church on the site of the present Kirk can be found in a Papal document of 1151.

The 500th anniversary of the dedication of the enlarged church was marked with the installation of a special stained-glass window at the main entrance to the Kirk, overlooking Drum's Aisle.

The church was rebuilt and a massive granite tower erected over the intervening aisles, a new carillon of 36 bells, cast in Belgium, being installed to commemorate the Victorian jubilee of 1887.

The foundations of earlier phases of the Kirk, many medieval burials, and large numbers of architectural fragments are among the rich finds from this important site.

[6][7] Despite the many alterations to the fabric of the Kirk over the year's, St Nicholas retains a larger number of medieval effigies than any other Scottish parish church, though none of these are in their original positions.

Close to the church on its south side a number of ground slabs now form part of paving, and are also used for car parking, a feature generally unseen in Scotland.
