"The tourists travel into those cities, in which there are a lot of church."

Translation: Azokba a városokba utaznak a turisták, amelyekben sok templom van.

[Kathy979841]

For those learning English churches has to be plural in english after a lot of

[mizinamo]

because churches are countable.

("a lot of water" is fine, for example; it does not have to be "a lot of waters")

[Kathy979841]

[vvsey]

Yes. Any number or quantity or similar things, however vague or specific, all require singular.

Why doesn't utazik also take the preposition be to indicate this movement into?
