Steiner Tor is a-preserved gate, originally built in the late 15th century but refashioned in the Baroque style in the city of Krems an der Donau, in the Wachau valley. It is considered the symbol of the city. Until the last third of the 19th century, the city of Krems was surrounded by a wall. This was systematically razed, and three gates were also removed. From 2005, celebrating the 700-year anniversary of the city rights, the Steiner Tor was restored as much to its original as possible.
Outside the portal are towers flanking both sides, which, like the lower floor of the gate, date from the late Middle Ages. On the right of the archway is a small stone coat of arms mentioning Emperor Friedrich III, and the year 1480 in Roman numerals. This is believed to date the restoration of the fortifications that had become necessary because of the destruction wrought by Hungarian troops in 1477. The tower building dates from much more recently, and dates to the Baroque period during the reign of Maria Theresa, 1756. Outside the gate, the Steiner Tor was originally threatened by flooding from the Danube. On the inner side of the stone door is a mounted memorial which commemorates such a disaster in 1573.
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.
