FOUNDATION

Establishes the core vocabulary and essential context you need before going further.

Discover the fundamental forces of tension plus compression governing every structure from history.

Station 01: Why Ancient Buildings Stay Up

Examine how early civilizations utilized sun-dried bricks for massive urban construction projects.

Station 02: The Strength of Mud and Straw

Investigate the precise stone-cutting techniques used in Egyptian pyramids for perfect stability.

Station 03: Stacking Stones Without Glue

CORE CONCEPTS

Unpacks the ideas and principles that the subject is built on.

Master the geometry required to redirect vertical weight into horizontal thrust through arches.

Station 04: The Invention of the Arch

Analyze how ancient carpenters developed complex trusses to support heavy roofing materials.

Station 05: Timber Frames and Roofs

Explore the chemical composition of volcanic ash mortar used in massive Roman harbor structures.

Station 06: The Secrets of Roman Concrete

Evaluate how the Doric and Ionic orders dictated weight distribution in classical temples.

Station 07: Columns and Greek Proportions

MECHANICS

Examines how things actually work — the processes, rules, and systems in action.

Synthesize arch mechanics to understand the construction of the Pantheon’s massive concrete dome.

Station 08: Vaults and Domes in Practice

Compare the structural requirements of stone aqueducts against simple wooden bridge designs.
