The Puente de Alcántara is a Roman arch bridge in Toledo, spanning the Tagus River. The word Alcántara comes from Arabic القنطرة (al-qanţarah), which means 'bridge'.
Located at the feet of the Castillo de San Servando, the bridge was originally built by the Romans after they founded the city. It was rebuilt by in the 9th and later in the 13th century by Alfonso X el Sabio. In the Middle Ages it was one of the few entrances of the pilgrim into the city.
References: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.
