The 'Ravelijn op den Zoom' (ravelin) is the last remnant of the fortifications designed by Menno van Coehoorn. The ravelin consists of a island with earthen and stone walls, surrounded by a wide moat. The ravelin is one of the few remaining parts of the extensive fortification system around the city. The fortress was so ingeniously designed that it was assumed that it could not be taken and therefore got the nickname 'La Pucelle' (Virgin). In 1747 the city nevertheless became occupied by French troops.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.
