The earliest reference to the Rhyl Botanical Gardens is in 1878 when it was sold by R. D. Roberts at public auction. Between 1878 and the 1920s there were several owners but in the 1920s the site was acquired by Rhyl Urban District Council and the Botanical Gardens were opened to the public in 1928. The gardens were famous for the rose gardens and a rose pergola. There was also a floral sun dial, a cafe and sports pavilion. The gardens declined from the 1970's, but from c.2004, restoration work has been undertaken.
