Followed one of the Cambridge Sculpture Trails in the City centre last week. Mixed media and varying quality. Highlights: Jester 1994, Wendy Taylor; Slate Work South Side 2016, Ackroyd and Harvey; Earthbound: Plant 2003, Anthony Gormley; and Between the Lines, 2007, Peter Randall-Page. But for all the clever artifice, nothing matched the huge plane tree that has marched slowly across the Fellows’ Garden at Emmanuel College over the past 300 years.
