Which town (city) was said to have been the place of residence chosen by the mother of Christ after his crucifixion?

Hi Mozart,
I think the answer is Ephesus, in what is now Turkey:
It is believed by many Christians and Muslims that Mary, the mother of Jesus, was taken to this stone house by Saint John and lived there until her Assumption into Heaven
House of the Virgin Mary

That's right dance girl. thanx

Moreover, it was at the Council of Ephesus in 431 that Mary was officially proclaimed Theotokos "God-bearer".
