Real Cool History for Kids

Episode 172: The Leeeeeaaaning Tower of Pisa (a special episode for Monty Goeller)
Host: Angela O’Dell
Release Date: January 26, 2026

Episode Overview

In this special episode requested by listener Monty Goeller, Angela O’Dell takes listeners on an engaging journey through the story of the Leaning Tower of Pisa. Told from a biblical worldview and in a kid-friendly, narrative style, Angela uncovers the history, engineering mishaps, and enduring legacy of this world-famous monument. Through the story of the Tower, she also draws parallels to the importance of building strong foundations in life, inspired by the teachings of Jesus.

Key Discussion Points and Insights

1. Introduction and Context of the Leaning Tower

• The episode opens with Angela painting a vivid picture of the Leaning Tower and the jokes and popular perceptions that surround it.
• Angela O’Dell [00:56]:
  “The real story of this tower isn't silly at all. It's actually really interesting. It's a story about patience and problem solving in a building that became famous not because it was perfect, but because it wasn't.”
• Pisa in the Middle Ages was a wealthy, influential city-state vying with rivals like Genoa and Venice.
• Pisa’s ambitious cathedral complex (the Piazza del Duomo) was designed to showcase their status, including:
  • A cathedral
  • A baptistery
  • A cemetery
  • The iconic bell tower (the Leaning Tower of Pisa)

2. Construction Begins: A Plan Gone Sideways

• Construction starts in 1173, with the original intention of building a tall, straight bell tower.
• Bell towers were crucial in medieval cities to mark time and signal events.
• Early progress is smooth, until the builders notice a worrying problem:
• Angela O’Dell [03:19]:
  “One side of the tower was sinking slightly into the ground, and the tower wasn't straight anymore. It was beginning to lean.”
• The cause: The ground underneath (a mix of clay, sand, and silt) was too soft to support such a heavy structure.

3. Engineering Challenges and Decades of Delay

• The workers of the 12th century didn’t understand soil mechanics like we do today, but they quickly realized the growing risk.
• Construction halts for decades.
  • Some of the pause is due to concern, but Pisa’s wars and shifting resources also slowed progress.
• When work resumed, builders face a hard choice: start over or continue? They choose to keep building, attempting to correct the lean by making one side taller than the other.
• Angela O’Dell [05:13]:
  “There's a subtle curve to its shape. Even with these adjustments, though, the tower never became straight.”
• The project spans generations; many original builders never saw completion.

4. The Tower’s Reputation Grows

• The Tower is finally finished in the 1300s, nearly 200 years later, still very much leaning.
• Over centuries, it survives storms, earthquakes, and wars, though the tilt worsens.
• By the 1900s, engineers fear imminent collapse, spurring urgent action.

5. 20th-Century Rescue Mission

• In 1990, the tower closes to visitors for preservation work.
• An international team works to save it, aiming not for perfection but for stability:
• “Their goal was not to make it perfectly straight. By then, the lean was part of the tower's identity. They just wanted to make sure it would stand safely for hundreds of years to come.” — Angela O’Dell [08:28]
• Engineers employ counterweights and under-excavation (removing soil beneath the high side) to reduce the lean carefully, only a few millimeters at a time.
• The process takes over a decade, with the tower reopening in 2001 after reducing its lean by about 17 inches.
• By 2008, studies confirm the tower has stopped moving and is stable.

6. Parable and Meaning: Lessons from Pisa

• Angela draws a spiritual parallel to Jesus’ teaching in Matthew 7: building on solid rock versus sand.
• Angela O’Dell [10:37]:
  “If you think about the fact that the Leaning Tower of Pisa was built on sand instead of rock, it's no wonder that it's leaning right? ... That tower, you guys, is kind of like our lives. If we want a strong, straight, functional and worthy life, we need to obey the word of God and build our lives on the rock of Jesus Christ. Anything else is like building our lives on sand that can be washed away or at least end up looking like the Leaning Tower of Pisa.”

Notable Quotes & Memorable Moments

• On what made the tower a marvel:
  “It's a story about patience and problem solving in a building that became famous not because it was perfect, but because it wasn't.” — Angela O’Dell [00:56]

• On the sinking discovery:
  “One side of the tower was sinking slightly into the ground, and the tower wasn't straight anymore. It was beginning to lean.” — Angela O’Dell [03:19]

• On intergenerational effort:
  “Parents worked on it, and then their children, and then even their grandchildren. The Leaning Tower of Pisa was built in sections, so not all at once.” — Angela O’Dell [05:29]

• On the tower’s legacy:
  “The tower has remained upright, although it has been crooked and leaning almost since the beginning. Its entire lifespan has been spent either causing worry for those around it or being worked on to keep it from tumbling down.” — Angela O’Dell [11:13]

• Spiritual comparison:
  “If we want a strong, straight, functional and worthy life, we need to obey the word of God and build our lives on the rock of Jesus Christ. Anything else is like building our lives on sand that can be washed away or at least end up looking like the Leaning Tower of Pisa.” — Angela O’Dell [11:43]
