Cadw's description

Immediately W of Conwy station and directly beneath the E side of Upper Gate Street.

On the Chester & Holyhead Railway, and built in 1845. Its chief engineer was Robert Stephenson, and contractor for the Conwy section was John Evans. Conwy tunnel was the site where the ceremonial first sod of the railway was cut on St David's Day, 1845. This section of the line opened in 1846.

Portal of snecked rock-faced stone with lighter grey tooled stone jambs and voussoirs to a round arch. A corbel table is at the base of the parapet, which also has 2 light-grey freestone bands (mostly obscured by vegetation at the time of survey). The stepped parapet has saddleback copings.

Listed for its special interest as a tunnel portal of definite mid C19 architectural character, one of a number of items contributing to the overall historical integrity of this section of the former Chester & Holyhead Railway.
