Garden Focal Point

We went out of town last weekend and I loved it even though the long drive is so tiring. We went to this place where there was a big fountain in front of the building. It was so nice and birds would come to the fountain and drink water from it. Having waterfall fountains in front of our garden makes it look beautiful , fountains truly soothe us and they are the focal point of the garden . I only see very few houses in this neighborhood have fountains in their yard or garden, I wonder why?
