Originally a narrow street continuing the line of Coney Street and Spurriergate on to Castlegate and the Castle. Widened in the 18th and 20th centuries it is one of the shortest of the 'gates' at barely 30 m (100 ft) long.

Crossing ahead is Ousegate, Low Ousegate (busy road) to the left leads to Ouse Bridge and Micklegate, High Ousegate (pedestrianised) to the right leads to Pavement. Straight ahead is Spurriergate (pedestrianised) leading to Coney Street and St. Helen's Square.

Nessgate is a busy road during the day.
