During the summer of 2014, Adina Hoffman set out through the streets of Jerusalem in search of an elusive British Mandate-era architect named Spyro Houris. In this excerpt from her book, Till We Have Built Jerusalem, she recounts aspects of her quest to discover who this “most outstanding Arab architect” of the period really was.As she looks for him, she also reckons with the legacies of various other Jerusalemites whose identities were (and still are) much more layered than any single ethnic or national label might indicate.
