St Nick's Church is an active church and stands in the centre of Durham, just down from the the Cathedral.
The original church stood on the north side of the square but was a plain structure. This was replaced by the current handsome structure in 1858. It is built of stone, and consists of a nave and a chancel, each with a north and south aisle. The tower, through which is the main entrance, stands on the south side of the building, and is terminated by a fine spire 160 feet high.
Inside is a very modern church, with good lighting and the stage in the middle as opposed to being at the end.
Adjoined to the church is a decent little shop which does the usual sort of church wares.
The market square itself is pleasant but always bustling. You're surrounded by shops, and an archway leads off into the market proper.
The area can be regarded as the heart of Durham, and you cannot fail to pass through as you tour the town.
