Text: The top of the tower is off limits, due to dangers inherent in the narrow staircase that leads to the look-out point, so the best bet for a panoramic view of the city is the top floor of one of the taller, more recent hotels.
Entailment: The narrow staircase at the top of the tower is so dangerous that they closed it off.
Contradiction: The best view of the city can be easily achieved by climbing to the top of the tower.
