The Kammerzell House is one of the most famous buildings of Strasbourg and one of the most ornate and well preserved medieval civil housing buildings in late Gothic architecture in the areas formerly belonging to the Holy Roman Empire.
Built in 1427 but twice transformed in 1467 and 1589, the building as it is now historically belongs to the German Renaissance but is stylistically still attached to the Rhineland black and white timber-framed style of civil (as opposed to administrative, clerical or noble) architecture.
It is situated on the Place de la Cathédrale, north-west of the Strasbourg Cathedral, with whose rosy colour it contrasts in a picturesque way when seen from the opposite direction.
The building's inside has been decorated on all floors by lavish frescoes by Alsatian painter Léo Schnug (1878-1933). It now houses a restaurant.
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.
