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 Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
