Join your host, Professor Mark Keane, for an engaging draw-along sketching session focused on the architecture of UNESCO World Heritage Sites. First, learn how to use perspective, the horizon line and the vanishing point to sketch the iconic Hagia Sophia in Istanbul, then practice collapsing a 3D figure into a 2D sketch. During the episode, Professor Keane also delves into the details of this iconic Turkish structure and reveals how it has changed over time—from a cathedral to a mosque.
