Niujie Mosque takes its name plainly from its location, the Oxen Street quarter of Beijing that has been home to a settled Hui Muslim community since at least the tenth century, when the mosque was first established under the Liao dynasty. The Hui, one of China's officially recognized ethnic minorities, are Chinese speaking Muslims whose communities trace back centuries along the trade routes that connected China to the Islamic world, and Niujie's mosque has served that community continuously, through repeated rebuilding and expansion, for roughly a thousand years.
What strikes most visitors first is how little the building looks like a mosque in any form familiar from the Middle East or South Asia. Its exterior follows Chinese temple architecture closely, with upturned eaves, painted timber brackets and courtyard halls arranged in the sequential style typical of Chinese religious and palace buildings. Only inside does the building declare its function: the main prayer hall is oriented toward Mecca rather than along the axis a Chinese temple would normally follow, arranged for the rows of communal prayer Islamic worship requires, with calligraphic Quranic inscriptions replacing the imagery a Buddhist or Daoist temple would carry.
That fusion is characteristic of mosque architecture built by China's long settled Hui communities generally, a visible record of a religious minority that adapted the building vocabulary available to it. The mosque has anchored its neighborhood through the full span of that history, surviving dynastic change, foreign occupation and the disruptions of the twentieth century to remain both a working mosque and one of Beijing's oldest continuously used religious buildings of any tradition.
