When the first humans settled in Ronda they were drawn to it because it is an easily defensible place. It's almost completely surrounded by rocky cliffs as much as 100 meters high. This was successful, Ronda fended off all attackers, but only until their Achilles heel was discovered, their source of water. Lack of water made Ronda surrender.
Today, of course, Ronda's invaders are tourists. Ronda offers a comfortable combination of touristy and real. The city is clean and well maintained and takes advantage of it's beauty and history. Broad paths track along the cliffs, plus there are paths down to the valley below.
The small, historic old town connects to the newer and larger part of the town via a centuries-old stone Puente Nuevo (new bridge). This bridge was built over the period 1751 to 1793 so it is new only in relation to the other two bridges in town which are far older, the Puente Romano (Roman bridge) and the Puente Viejo (old bridge).
In addition to the cliffs and the bridges, there are attractions such as Moorish baths; Spain's oldest bull fighting ring; and churches and squares and well-priced restaurants. The bull fighting ring is still in use and attractive. Ronda is quite romantic and not without a hint of danger. You can't help think it would all come tumbling down were there an earthquake. But not a bad place to be should there be a zombie apocalypse.
