Dominician Church History in Lviv

Hi :)

I've visited Lviv recently and Dominician Church was on the sightseeings that captured my attention.

A guide said that this church was brought to Ukraine by a Hungarian Princess. and that's all I know about it (except its origins).

I'd like to know more about the church. and the names of the prince and the hungarian princess... and as much as possible about their relationships..

It's a wonderful story, I think and want to share it with other people.

If anyone could help with the information around this church that would be terribly kind of him/her.

Thanks for attention.
