This is the entrance to Dalt Villa (Catalan for 'Upper Town') which is the oldest part of Ibiza Town. Once the island was reconquered from the Moors by King James I of Aragon, the fortress was outfitted and a wall encircling the whole city was constructed and completed in the thirteen century. The steeple of Santa Maria d'Eivissa can be seen in the upper left, the pinnacle of Dalt Villa constructed in the fourteen century. I found it delightful to walk out of the drawbridge every morning to sit at a café and drink in the shade. After a long night out, it felt save to sleep in a town that had its own fortress walls.
