The ashlar tower is 14.6m (48ft) high and was designed by the civil engineer John Rennie in 1821. The tower has survived intact, preserving its lantern, probably the second oldest in Wales. It is surrounded by beautiful curved gallery railings.

Event and Historical Information:
It replaced an earlier tower illustrated by Daniel, the successor of a thatched structure of which unfortunately no more is known. Rennie also designed a matching tower at Howth in Ireland for the other terminal for the Irish packet. It was no longer used after the pier was extended. The end of the lengthened pier is marked by a light on a pole.
