The concept of memory is important in architecture and placemaking, and an exploration of the morphology of context and historic typologies helps to create a dialogue between the reassurances of the past and the ever changing patterns of 21st Century life. Published to coincide with the 2017 London Festival of Architecture and the theme of Memory, we are pleased to present the thoughts on memory from a range of writers, through four short essays; from the sampling techniques of Hip-Hop musical subculture to the role architecture plays in its ability to trigger a lifetime of memories in the twilight of life.
