The Maribor Water Tower is a late-Renaissance tower dating from 1555. It is of pentagonal form and consists of massive stone blocks interspersed with embrasures. It was built to secure the southeast part of the Maribor city walls from the direction of the river.
At present, the Water Tower houses a wine shop which specializes in top-quality Slovenian wines. It is Slovenia's oldest wine cellar, and is situated in what is now the center of Maribor. The shop is on the ground floor. The top floor of the tower contains a large, round hall with a high ceiling, reminiscent of a medieval banquet hall, which is dedicated entirely to wine tasting. The world's oldest grapevine is located on the side of a building a few hundred m away.
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.
