Caernarfon's town walls are a medieval defensive structure around the town of Caernarfon in North Wales. The walls were constructed between 1283 and 1292 after the foundation of Caernarfon by Edward I, alongside the adjacent castle. The walls are 734 m long and include eight towers and two medieval gatehouses. The project was completed using large numbers of labourers brought in from England; the cost of building the walls came to around £3,500, a large sum for the period. The walls were significantly damaged during the rebellion of Madog ap Llywelyn in 1294, and had to be repaired at considerable expense. Political changes in the 16th century reduced the need to maintain such defences around the town. Today the walls form part of the UNESCO world heritage site administered by Cadw.
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.
