In the cities, people lived in rows of rectangular houses laid out in rows, built of wood and rammed earth. Rammed earth is just dirt that’s been packed down hard by pounding on it, like packing the sand into the bucket to make a sand castle. In the center of the city, there was a big palace or temple (nobody is sure which) on a high earth platform like the earlier Sumerian ziggurats. One building at An-yang was a big hall with pillars all the way around it, about the size of a modern basketball court (though the Shang Dynasty emperors didn’t use the building for basketball!).
There was another building a lot like this one at Panlongcheng. Both buildings probably had thatched roofs. You might compare this building to early Greek temples from around 800 BC, which also have wooden columns all the way around them and thatched, slanted roofs. Those Greek temples were built later than these Chinese ones.
