"הכנסייה נמצאת במרכז העיר."

Translation: The church is in the city center.

[houthakker72]

Should probably also accept:

The church is in the centre of the city

[JudithMett2]

... and ' is located... '

ha-cnesiah neemtzet b-mercaz ha-ir

[clement2609]

Just like the Turkish word merkez

[Ricard105682]

And the Persian word merkaz

[Ricard105682]

Why not 'ba merkaz' as it is definite (at least in English)

[danny912421]

Because it is in construct state מרכז עיר - city center, and in construct state only the second word gets ה, so even when it is definite, it will alway be be-merkaz.
