# Jericho's First Fortification

> Jericho's tower and walls represent the earliest monumental defensive architecture, indicating organized territorial conflict and communal labor coordination.

Around 9000 BCE, the inhabitants of Jericho built the first known defensive wall, a 7-meter-high structure of stone that encircled their settlement in the Jordan Valley. This fortification marked a decisive shift: humans were no longer just settling in permanent towns, but actively defending them, signaling both the value of accumulated resources and the emergence of organized conflict.

## Summary

Jericho Historic District is a national historic district located at East Hampton, New York in Suffolk County, New York. The district includes three contributing buildings. They are three early the 19th century, Federal style residences; the remnants of a historic settlement known as "Jericho." All are built of heavy timber-frame construction with shingled exterior sheathing.

## Key facts

- **Wall height**: Approximately 7 meters
- **Settlement population**: Estimated 600–2,000 inhabitants
- **Wall circumference**: Roughly 270 meters
- **Archaeological period**: Pre-Pottery Neolithic A (PPNA)
- **Construction material**: Fieldstone
- **Tower discovery**: Round tower approximately 9 meters in diameter, interior staircase of 22 steps
- **Location**: Jordan Valley, West Bank, near modern Jericho

## Timeline

- **9100-09000-01-01** - Pre-Pottery Neolithic settlement established
  Early Jericho shows evidence of permanent habitation without ceramic production, relying on hunting and gathering with emerging cultivated plants.
- **9000-01-01** - Stone fortification wall constructed
  A massive defensive wall built from fieldstone encircles the settlement, approximately 7 meters high and 270 meters in circumference, marking the earliest known monumental defensive architecture.
- **8900-01-01** - Round tower added
  A circular tower structure approximately 9 meters in diameter, featuring an internal staircase of 22 steps, is constructed near or integrated with the defensive wall system.
- **8800-01-01** - Wall maintenance and rebuilding cycles
  Archaeological evidence indicates multiple phases of wall reconstruction and reinforcement, suggesting sustained threat perception and community commitment to defense.
- **8000-01-01** - PPNA settlement transitions
  Jericho enters the Pre-Pottery Neolithic B period; architectural patterns shift and the intensive focus on fortification wanes as settlement dynamics change.

## Impact

Jericho's fortification revealed that organized defense infrastructure emerged thousands of years earlier than previously understood. The wall's existence redefined how archaeologists conceived of early urbanism, property, and the social coordination required to construct monumental architecture before pottery or agriculture had fully developed.
