Ulm Minster, like Cologne Cathedral, was begun in the Gothic era and not completed until the late 19th century. It is the tallest church in the world, and the 4th tallest structure built before the 20th century, with a steeple measuring 161.5 metres. From the top level at 143m there is a panoramic view of Ulm.
The foundation stone was laid in 1377. The planned church was to have three naves of equal height, a main spire on the west and two steeples above the choir. In 1392 Ulrich Ensingen (associated with Strasbourg Cathedral) was appointed master builder. It was his plan to make the western church tower the tallest spire, which it remains in the present day. The church, consisting of the longitudinal naves and the choir, covered by a temporary roof, was consecrated in 1405. However, structural damage, caused by the height of the naves and the weight of the heavy vaulting, necessitated a reconstruction of the lateral naves which were supported by a row of additional column in their centre.
In a referendum in 1530/31, the citizens of Ulm converted to Protestantism during the Reformation. Ulm Minster became a Lutheran church. In 1543 construction work was halted at a time when the steeple had reached a height of some 100 metres. The halt in the building process was caused by a variety of factors which were political and religious as well as economic. One result was economic stagnation and a steady decline, preventing major public expenditure.
In 1817 work resumed and the three steeples of the church were completed. Finally, on 31 May 1890 the building was completed.
A devastating air raid hit Ulm on 17 December 1944, which destroyed virtually the entire town west of the church to the railway station and north of the church up to the outskirts. The church itself was barely damaged. However, almost all the other buildings of the town square (Münsterplatz) were severely hit and some 80% of the medieval centre of Ulm was destroyed.
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.
