Step-by-step explanation:
The Pavilion of Senusret I at Karnak is an Egyptian architectural structure from the Middle Kingdom. It is not an example of a medieval European castle, an ancient Roman amphitheater, or a modern skyscraper in New York City.
The Pavilion of Senusret I is a part of the larger Karnak complex, which was a religious center dedicated to the god Amun-Re. The complex features several unique architectural features, including the famous Hypostyle Hall with its massive sandstone columns.
These columns supported the roof of the hall, and the spaces in between allowed clerestory lighting, which was a unique feature of Egyptian architecture.
