Zahara de la Sierra Castle is actually a six-hectare area on the rocky hill, known as the Villa Arabe or Villa Medieval; its crowning glory is the Homage Tower. The town was originally a Moorish outpost, overlooking the valley. Due to its position between Ronda and Seville, it was a perfect site for a castle to be built to serve as a fortress in case of attack.
The path starts at the car park on the roof of Hotel de la Villa and is wide with a handrail in good condition. It is a steep climb through the cacti and pines with wild flowers, prickly pear and almond trees. Initially you pass by foundations of unmarked buildings clinging on the more level slopes. The first historic building looks like the homage tower but is the Iglesia Major and you still have a long way to climb. Be careful here as the birds nest in the walls and make a mess on the path or persons below. The supporting buttresses are modern but the walls are original.
The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
