Mesopotamian Architecture & City Planning
1. Urban Layout & City Planning
   ● Mesopotamian cities were planned and fortified, built around central religious and
      administrative structures.
   ● Cities were located near rivers for water supply, irrigation, and trade.
   ● Main features of city planning:
          ○ Ziggurat (Temple Complex): Center of religious and civic life.
          ○ Palaces: Residences for kings and administrative centers.
          ○ Defensive Walls: Thick mudbrick walls for protection from invasions.
          ○ Canals & Irrigation: Advanced water management systems.
          ○ Markets & Residential Areas: Houses, workshops, and open-air markets.
          ○ Wide Processional Roads: Used for religious and royal ceremonies.
2. Building Materials & Construction Techniques
   ● Mud Bricks: The primary building material (due to lack of stone and wood).
   ● Reed & Bitumen: Used for roofing and waterproofing.
   ● Brickwork Innovations:
          ○ Baked bricks for durability.
          ○ Glazed bricks (especially in Babylon, with colorful depictions of animals and
             gods).
3. Key Architectural Structures
A. Ziggurats (Religious Temples)
   ● Pyramid-like stepped structures dedicated to gods.
   ● Built with solid mudbrick cores and baked brick facings.
   ● Featured staircases or ramps leading to the temple at the top.
   ● Example: Ziggurat of Ur (c. 2100 BCE).
C. Defensive Walls & City Fortifications
   ● Massive walls surrounded cities to protect against invasions.
   ● Often had gates with elaborate carvings (e.g., Ishtar Gate in Babylon).
   ● Some cities had moats and watchtowers for added security.
D. Residential Houses & Streets
   ● Homes were built from mud brick and had flat roofs.
   ● Common layout:
          ○ Small rooms surrounding a central courtyard.
          ○ Few windows to protect from heat and dust.
          ○ Wealthier homes had multiple floors and decorated walls.
   ● Streets were narrow and winding in lower-class areas, while main roads were wider
      in elite districts.
E. The Hanging Gardens of Babylon (Possibly Mythical)
   ● Described as a lush, terraced garden built by King Nebuchadnezzar II (6th century
      BCE).
   ● Thought to have used an advanced irrigation system.
   ● No archaeological evidence yet, but Greek historians recorded its existence.
