The Grade I Royal Liver Building in Liverpool opened in 1911 and was one of the first buildings in the world to use reinforced concrete.
Atop each tower stand the mythical Liver Birds, designed by Carl Bernard Bartels. The birds are named Bella and Bertie, looking to the sea and inland, respectively. Popular legend has it that while one giant bird looks out over the city to protect its people, the other bird looks out to sea at the new sailors coming in to port. The building is crowned by a pair of clock towers: as a ship passed along the river, mariners could tell the time from these.
