This very special collaboration has been influenced by the Natural History Museum’s incredible building. First opened in 1881, the Museum is now considered a work of art in its own right. Alfred Waterhouse, a young architect from Liverpool, used a mixture of Gothic Revival & twelfth-century Romanesque-style architecture, in line with Museum founder Sir Richard Owen’s vision of creating a ‘cathedral to nature’. Taking inspiration from the Museum’s unique architectural details & unmistakable Victorian décor, our contemporary collection makes it possible to bring a piece of natural history into your home.© The Trustees of the Natural History Museum, London 2022.
