Yìzhōuzhàn
Yizhou was an old fortified centre west of the Liao River, associated with a Liao imperial princess and the households under her authority. Its site at Tayingzi preserves a Liao pagoda, a reminder of the Buddhist patronage of the families who held power here. A road ran east from Yizhou toward Kaiyuan, passing through other old towns. It remained an important route in Yuan and Ming times, with stations serving travelers along the way.
