Why go
A high platform, northern stair and ornate annex seem at first like separate pieces. The construction sequence ties them together: a small rounded platform grew taller, received rooms, and was joined by the annex before further levels were built. The contrast between plain upper mass and detailed façade is the payoff.
The full story
The complex began with a low platform with rounded corners and a projecting southern stair. Its remnants are visible in a large collapsed opening on the western side. The platform was raised to roughly twice its first height and gained a one-room building with three north-facing doorways. Builders then added the eastern annex, initially arranged as thirteen rooms in three parallel rows with a crosswise room at the end. Its façade carried a high base and elaborate horizontal bands; one band stepped around a false serpent-mouth entrance, with woven patterns and ik signs, often associated with wind. Later work enlarged the upper building from one room to eight and added a north stair toward a still higher, plainer one-room structure. The sequence explains why the present mass combines different heights and decorative vocabularies. The historic room count and circulation describe the building's development; they do not imply that its rooms are open for entry.
