I thought that f. ex. "Where did you visit in England?" is incorrect, and we should say something like "Which/what places did you visit in England?" as visit is a transitive verb.

Are there situations where "where" and "visit" can be used together?
You can use where in a dependent clause.

He visited the places where he used to live.

Thank you for the answer, but maybe you misunderstood my question. I was wondering if "Where did you visit?" is correct English. I thought it was wrong, but, look, a native speaker uses it here f ex. http://www.msnbc.msn.com/id/20779475 /
It's not incorrect, just unusual.
It might be used for emphasis.

Just (exactly) where did you visit in England?
