Representations of the bird can be found throughout Liverpool, most numerously on the heritage lamp standards in the town centre on which small versions sit as a top piece. The two most famous stand atop the clock towers of the Royal Liver Building at Liverpool's Pier Head, overlooking the Mersey. Their names are Bertie and Bella. The male, Bertie looks over the city and the female, Bella looks to the sea. The building, headquarters to the Royal Liver Assurance, was opened in 1911. The metal cormorant-like birds were designed by Carl Bernard Bartels and constructed by the Bromsgrove Guild of Applied Arts.
