Fira is the capital of Santorini and is built on the edge of a cliff which is, in fact, the rim of the crater. It is 900 feet above the landing port and about 800 broad, zigzagged steps up from the port. You either take the donkeys or mules up the winding steps or modern-day travellers prefer the cable car. Climbing the steps with a mule had been a tradition on Santorini for years, until 20 years ago when the cable car made its appearance.
