Gorgeous old Catholic property, now the Communist Chinese Embassy.
From Bishop Sheen in China:
"I gave a lecture at Aurora University and the next day gave a broadcast to China. I said that God had kept China behind a veil all these centuries and allowed it to keep a five-thousand-year-old culture to become one day a great Christian nation. After the broadcast, Bishop Walsh told me that Pius XI had told him that very idea some years before."
