Because cities have too much light pollution. They need to be in the dark - the darker the better. Also, when a ground based optical telescope (as opposed to a space telescope like the Hubble) looks up into the sky any image has to pass through the earth's atmosphere. In a city the air is often polluted and dusty, so looking through a telescope based there would produce a poor image - a bit like looking though a dirty window. On a mountain top the air is not only clean, but the atmosphere is less deep there because of the height of the mountain. The air above is less depth and cleaner so there is a better chance of a clearer image.
