Seiyun

Seiyun is the largest town of the Wadi Hadhramaut and the practical base for the whole valley, built around the sultan's palace of the Kathiri dynasty, an enormous white mud-brick building on a raised platform that is among the largest earthen structures anywhere. Its whitewashed walls and rows of shuttered windows dominate the town square. The palace now holds a museum of the valley's archaeology and the sultanate. Seiyun has the airport that serves Hadhramaut, and date groves stretch along the wadi floor in both directions. Most visitors sleep here and see the other wadi towns as day trips.
