Finding the Golden Ratio in Durham Cathedral



Maths teacher, Steve Humble, uncovers the golden ratio in the architecture at Durham Cathedral. Ideal for Key Stage 3 maths students.

Steve Humble examines how a cathedral like Durham was designed by following the master mason's use of practical geometry, symmetry, pattern and proportions.

Here, Steve investigates the proportions in Durham Cathedral and discovers ratios that are very similar to the golden ratio.

He encourages teachers and students to find examples of the golden ratio in their school buildings and local churches.

The video uses Northern Architecture's Making Architecture Count project for schools.
