Zorluk: KolayMegalithic Architecture and Sacred Spaces

How did the builders of the Pacific island site of Nan Madol construct the massive retaining walls of its artificial islets?

  1. A
    By erecting vertical monoliths topped with horizontal lintels joined by carved mortise-and-tenon connections.
  2. By stacking natural columnar basalt in alternating header-and-stretcher courses with a core of coral rubble.Cevap
  3. C
    By shaping irregular stone blocks that fit together tightly without mortar to resist seismic activity.
  4. D
    By layering sun-dried mud bricks over a framework of projecting wooden poles for structural support.

Cevap

The builders of Nan Madol constructed the islet walls by stacking naturally formed columnar basalt in alternating header-and-stretcher courses, filled with a core of coral rubble.
The retaining walls of the artificial islets at Nan Madol were constructed by stacking naturally formed hexagonal columns of basalt in alternating parallel (stretchers) and perpendicular (headers) layers, filling the interior spaces with coral rubble to form stable platforms.

Adım Adım Çözüm

1
Identify the primary construction material and masonry method unique to the site of Nan Madol.
The site is constructed from naturally occurring columnar basalt and coral fill.
Recognizing the unique geology and masonry style of Nan Madol is key to distinguishing it from other monumental stone structures.
2
Compare the correct materials and assembly style against standard construction techniques of other ancient cultures.
Alternating courses of basalt columns (headers and stretchers) contrast with Stonehenge's post-and-lintel system, Inka ashlar masonry, and African mud-brick architectures.
Differentiating these techniques ensures mastery of Pacific megalithic architecture.
