It is part of the Liverpool Maritime Mercantile City UNESCO World Heritage Site, which was inscribed in 2004. The site encompasses a trio of landmarks, built on the site of the former George's Dock and referred to since at least 2000 as "The Three Graces": Royal Liver Building, built between 1908 and 1911 and designed by Walter Aubrey Thomas. It is a grade I listed building consisting of two clock towers, both crowned by mythical Liver Birds. The building is the headquarters of the Royal Liver Friendly Society. Cunard Building, constructed between 1914 and 1916 and a grade II* listed building. It is the former headquarters of the Cunard Line shipping company. Port of Liverpool Building, built from 1903 to 1907 and also grade II* listed. It is the former home of the Mersey Docks and Harbour Board. Also on the site is the grade II listed Mersey Tunnel building, to the east of the Port of Liverpool building. It was built in the 1930s and contains offices and ventilator equipment for the Queensway Tunnel.
