SeaQuarium, Rhyl

Opened in 1992 as the Rhyl Sea Life Centre, this attraction was situated on the Rhyl promenade. It showcased various species from around the world across nine different zones, along with an outdoor Seal Cove where visitors could meet harbour seals in a large pool filled with 330,000 litres of water. For many years, the centre operated under the Sea Life brand, part of the Merlin Entertainments group, until it was sold to SeaQuarium Ltd, which also owned the Weston-super-Mare site that has since closed. The centre was popular, drawing in tens of thousands of visitors annually and employing around 20 staff. Unfortunately, in November 2023, it announced it would shut down, with its final day of operation on 27th November. Following the closure, the animals were relocated to other aquariums.

SeaQuarium cited the ongoing coastal works by the council as the main reason for the closure. They claimed these works would negatively affect trade and cause welfare issues for the seals. After the closure, Denbighshire County Council applied for approval to demolish the building. In their planning documents, they stated that the structure was outdated as a modern tourist attraction. Although the council recognised the prime location of the building, they noted it required significant investment. Demolition began on 7th January 2025, with work expected to take about six weeks.
