It seems at first that architecture is almost eternal but there are thousands of examples when buildings disappear and no history is left, and no-one remembers.
Castle market in Sheffield, the United Kingdom by architects Andrew Darbyshire and L. Womersley is a great and sad example of disappearing modernist architecture.
It was named after Sheffield Castle, which was almost entirely demolished in 1648 but the remains of the 13th-century foundations were still visible beneath the market and could be visited.
After research done on both, the castle and market, the image was designed to represent the idea of fragility in the form and function of architecture.
