This walk behind Holborn’s main roads takes us through garden squares and tree-lines streets. Queen Square with its many hospitals and educational associations, Red Lion Square, laid out by the first professional, female landscape gardener. We pass architectural gems including the John Soane Museum, and through Sicilian Avenue; see monuments to social reformer Margaret MacDonald, radical politician Fenner Brockway, and the church with a king on its spire close by early social housing and the hotel that started life as a hostel for young women before finishing at the British Museum.
