Yes, an observatory usually refers to an area devoted to watching heavenly bodies. Very often the observation decks are merely referred to as observatories so the confusion. I have seen the Burjs' decks referred to as observatories. So it seems the decks were built over 1,000 ft. from the pinnacle as the building is too narrow to accomodate an observation deck. I disagree. The Empire State Bldg has their observation deck directly under the spire. Their 2 decks are extremely small and limited but they are truly at the top. The ESB could have built their decks on the much larger 86th floor level to accomodate greater visitors.
